Bad Communication from Accounts

Since March 2015 I have requested my account be e-mailed as my box add was closed. They said no problem. After at least 1000 requests I received a copy of my account. I took off the interest and admin fees and paid. They now want all that interest and service fees paid. I refuse. If I had got the account when requested these fees would not be there. It has now gone from R291-84 to R300-00 odd. I am not paying this because I waited till August for the account. I get at least 2 - 4 call a day from them insisting I pay. What part of IF I HAD GOT THE STATEMENT WHEN REQUESTED NONE OF THESE FEES WOULD HAVE BEEN THERE. The account would have been paid in full at the end of April. I have now had enough. The one hand does not know what the other hand is doing. I need help desperately to get through to these people IT IS THEIR FAULT, NOT MINE. I WANTED TO PAY BUT COULD NOT GET AN ACCOUNT.
