PATHETIC service from Telkom Mobile Head Office

Hello Peter Could you assist me with the following case pls? I have taken out a cellphone contract with Telkom Mobile in April 2017. In February 2019 the company I used to work for went under liquidation. I only had two more instalments to pay on that contract but as I did not get payed out from the company I couldn't and I went into the store to state my case to them. The consultant told me they do not handle these cases in store and that I had to email their head office with proof of retrenchment letter and the liquidation letter with a certified copy of my ID document. I did that the very same day. After a month I saw they were still deducting from my account and I received threatening messages from them as I was unemployed. I went back to the same Telkom shop and asked them why they still deducting and sending me threatening messages. The consultant put me through to their head office on the phone in store and then I was told that my case is with their insurance department and its pending so i dont need to worry it will be covered. Up until now they still deducting from my bank account and it costs me to take an uber taxi to and from the bank to make the reversal and the bank charge me everytime for each reversal I make. I have a bad credit record because of them now and I have joined a law firm to hand my case over to them. Can you help me pls Peter ? Thanking you Ricardo Patel
