I signed a contract for a storage unit. I forgot to pay one month it went paid thirty days. I call the lady at the company she told me since my unit went over 30 day the company added $100 to my payment. I told her she didn't tell me that would happen if you go over 3O days. She said it's on the wall. Can I be made to pay the extra $100 if it's not stated in my contract. But stated on the wall and I didn't see it.
