Account Departments is USELESS.

Since I took the EXPLORA FIXED PLAN for R549 my account has been in arrears. From the start a debit order went off for the instalments and it was always more then the agreed amount of R549 a month. I cancelled the debit order and decided to make cash payment rather then I was getting ****** every month. After many telephonic conversations and emailing them through there portal they can not seem to sent me a proper statement through that summaries every payment that was made and the deductions that was made to bring my account into arrears. I decided to get out of the fixed contract to opt to buy myself out of the contract and give them a call today. I was informed that I must pay R2383.50 to buy out the contract. Now according to there accounting I have only payed R1192.50 0n the fixed plan to date. I need a summarised statement to show me how that is possible. I need a SUMMARRY.
