Had a reservation for a 26' truck. the truck was not on site when I arrived at the promised time. The manager gave me 2 choices; she could cancel my reservation, or find me a smaller truck and give me a $50.00 discount. I drove 2.5 hours to pick-up this truck and had people on the clock waiting to load it. The store manager called me an Uber and sent me to Union City to pick-up a 20' truck. This was completely unacceptable!!! The workers didn't seem to care that I had a bonified reservation for their store. If I ran my business like this, I'd be out of business!! I will do everything in my power to never rent from U-haul again, I will tell all my friends and business associates not to use your company. I own and manage a large real estate sales and management company with over 27 agents and manage over 450 units. I will make sure that they know of my experience.

The people that worked her were very friendly and knowledgeable. He apologized for there still being mud on the floorboard from the previous user. But it wasn't a bug deal to me. Uhaul screwed up my reservation and truck size but was not the fault of this location. It was the online service itself.

The people here asked me for my exact credit card number, the expiration, the security code? She was writing it down. I already prepaid over the internet and it should've just been a quick process and charge to my card automatically already, so I'm not sure why she was writing my credit card info again when I already prepaid online.

Don't change a person's pick up location!!! I reserved a truck at the Jackson St. location in Hayward but was told I had to go to another location to pick it up. Also, my email then changed my "preferred location" to the one U-haul decided, not me. Though the staff at this location were very nice and the truck was ready, I had to go way out of my way to get it ... I have made a complaint by phone and my reference ID# is 1630473. Though picking up the truck at a different location was very inconvenient and annoying, I do want to say every single staff person I encountered during pick up, drop off AND my phone call in the main office have been super nice and as helpful as they can be. I was told I should hear back from someone in the next few days. Thank you

Need to speed up with check-in, and reservation should be guaranteed especially when it was confirmed the day before..3 hours wait for a truck to become available upon my time of pick up, wasted my time and messed up everyone's schedules that was involved with helping me move that day. The man there was apologetic and given me a discount.. He was nice and helpful. But It is hard to say if I'd use them again, that was one stressful day I had to go through.

Truck had someone else stuff still in it. It had not been cleaned. Beads and broken glass in the back. Lady did a light sweep "I cannot see any more." The man got in and he did a better sweep but there were still beads rolling around. Front head light was out - the car I was following told me. Mud on floor boards of cab. A check light on the dash came on - image of a trailer. I do not know what that meant.

I ordered furniture pads but did not receive them when I picked up the truck. I didn't notice until after six so it was too late to call. I was originally charged for them but cleared it up with one of the workers and got the charge dropped for it. Would have been nice to get the pads, but no harm came to my furniture during transport so I'm not too upset over it.

maintain vehicle, make sure its safe to drive, the vehicle i rented shut down on the freeway completely without power, steering, and brakes. I thought i was going to die, good timing there was an exit during this situation and i used the E-brake to stop and pulled to the shoulder, all this going on while speeding cars were passing by. turns out, the pulley thats connected to the belt was put in incorrectly. totally unsafe and put me in a dangerous situation. hopfully someone from uhaul will respond or do something for me for all the hassle and inconvenience.

U-Haul Contract 82353875 Olmedo861@gmail.com Did not like the fact that i had no saying whether i wanted the insurance. It was mandatory for me to get it. I had a 3 mile trip and paid a little over 50.00. Other locations give u the option of declining.

The people at Diamond were excellent and it was a pleasure dealing with them. As was customer service (Candy) that steered me to them. Auto Style Company Hayward on the other hand was horrible. My auto reply told me this was where I was to pick up the truck but said I could not have it till noon. Needed to start earlier I called to see if I could pick up first thing in the morning. They flat out told me NO. And were rude so I was rude back honestly. But Candy with customer service found me a truck that I could pick up at 9:15 AM. and Diamond was just great when I went there to pick up the truck. You need more like Candy and Diamond and Less like Auto Style.
