bad attitude and falsely accusing a client

I emailed him the 17th of Jan to stop me and my boyfriends account beacuse we moved to somerset west in december. I received a phone call from him on 20 of Jan explaining the fees that in will need to pay. I told him and said I do not have the money then and will only be able to pay at the end of the month and asked if it will still remain the same amount. I dont want to pay anything extra and also dont want the debit order to go off. He assured me that I will only pay what he explained on the phone. I also arranged with him that I will then come in all the way from somerset west friday the 30th of Jan to pay and he agreed to no problem at all. When i got there he was not in the office. I tried to pay my account but Febr aleady went off and now I have to pay another month for gym when I dont even live in the area anymore. The person in charged phoned him. He was rude and unprofessional. According to him I am lying about everything and he has never said anything like that and that when I come at the end of the month I will have to pay for Febr never mentioned in our previous phone call. When I tried to set up a meeting to see him, he refused. I will only pay what he quoted me!
