Bad attitude and billing

After a misunderstanding with the amount due on my account and having a very rude person calling me from Foschini. I asked them to give me the full amount due on my account which I paid immediately and I then also informed them to close my account as I did not ever want to deal with them again. I now get a SMS from them to pay R 56.00 or my account will be handed over. I then phoned them and only to be transferred back and forth to various departments and every one giving me a different story as to how the amount ended up there. eg: billing charges or a booklet charge etc. and very rude people that just say they cant help. Never again will I deal or buy anything from the foshini group again and I will not recommend any one to deal with them either.
