TELKOM - STRUGGLE TO GET CONTRACTS CANCELED

Good day Telkom. Hope you are well, as I am certainly not. My account number is ********** 88. My contracts under this account number was supposed to be terminated Des 2017 as this was the end of the 24 month cycle. We have moved to New Zealand in Oct 2017 and thought it good to just leave the contract to run untill the end, which will be 2 months, but to my shock, I discovered Telkom STILL debits my bank account for the contracts. I've tried to contact customer services several times to cancel everything, as it was supposed to be terminated in any case. 29 March 2018 I did the cancellation online and received a confirmation email with a reference, ********** 7. Unfortunately that did not help as my bank account was still debited every month. On 7 May 2018, I contacted your customer services via the chat online service you have and I chatted to a Mashudu and asked him to follow it up for me. He discovered and told me that all my numbers on this account were blocked. BLOCKED BUT YOU STILL CHARGE ME EVERY MONTH AND ALL OF THOSE PAYMENTS WENT THROUGH. He told me that he will sent a request for it to be unblocked and then the cancellation will be possible. Well here we are, it is July and you still invoice me. Can you please tell me the way forward?can you please stop this contracts as it was supposed to be terminated Des 2017 and can you please tell me how long i will wait for my refund for the months money were taken from me for no service used?
