Refusal of Statements and Account Closure

We had a Standard Bank Cheque account for a while now. Our company opened a bank account with another bank. We tried to close our Standard Bank account but because we had facilities with Standard Bank they refused to close the account which is completely understandable. We have been paying amounts to this account and no matter how many payments we make, the amount owing never gets less. We have requested statement upon statement but Standard Bank is not forth coming with reconciliations and we cannot see what we are paying or if the amounts we have paid, have been taken into consideration. Every month extra charges and interest is added to this account and we just cannot seem to make any headway with payment because to date we still have not received statement.
