Business ProfileforMail Bank/Storage Bank

On the February 5th, I rented a storage unit on the second floor. The website stated that there was an elevator / lift. We wandered around the first floor and found several locked doors, so there might have been an elevator behind one of those doors. There is a very long set of stairs going up to the second floor, but there was no way I was going to carry large furniture and large appliances up those stairs. I called customer service was told that there should be an elevator there and she was going to look at a map/layout of the building. She stated she was not able to find one. I told her that the reason why I paid for the second floor was because it is $10 less per month and I am on a budget. The only reason why I went with the 2nd floor was because the website said there was a lift. I asked her if it was possible to transfer my lease to a 1st floor unit, and if could keep the lower price. She confirmed that she would be able to transfer my lease and not apply the more expensive monthly fee. After moving everything in, I received the email confirmation for the unit transfer and it shows that I will be charged for the more expensive rate rather than the cheaper rate that she promised I would be able to keep. Also, the promotion that I chose offered the first month at $1 and the second full month would be 50% off. I was correctly billed the $1 for the first month, but my account shows that the 2nd month will be full price. I called customer service again and the person said that she thinks I'll only be charged the 50% off price. I explained that I need to know for sure because I had to set up auto pay to get that promotion. I need to know that I will only be charged $75 next month and not $150. The lady said she cannot be positive because that location isn't exactly one that they directly manage. She said to call back during the week to see if someone locally can be contacted to confirm the pricing. I called again today and was once again told that they aren't sure.
