Contract Termination hassles and endless billing

I upgraded two contracts, one at the Nicol way branch and one at the Fourways branch expecting a monthly charge of about 650rand including a 3rd old contract. Surprisingly I got bills as follows:<br> 31 July R673 31 Aug R1533,67 30Sep R2389.93. On the 26th of September I phoned 808 and was told that the limit had not been set to zero at the Nicol way branch. I queried these amounts as per received statement on line and complained why the limit had not been set to zero. Ref ***. I did not receive a response and received a further bill end of October for 1205r. I made a request to terminate the contract and migrate to prepaid as the monthly amounts were ridiculously high. Ref ***5 I received the amounts for two of the contracts and paid in full on the day . (3628.08 plus 4242.82) I paid the exorbitant amounts to free myself from such abuse. I had also made a request for the 3rd completed contract to be migrated to prepaid on the 5th of Oct. This was only done on the 25th of Nov after much hassle and tussle. To my surprise, a debit order has gone through for MTN 31Dec15 R1095.44 . I have no communication regarding this amount. To date, I have paid R14768.02.
