Shame on You TELKOM.. deception to ***** money.

I had a Mobile data contract which I submitted a cancelation for on the 3 July 2020. The two year period expired on 23 July so I was told that I incurr a penalty due to the 30 notice period... I accepted that however on 25th August 2020 I still get a deduction taken out for almost the entire amount of subscription... I contacted my bank and had the deduction reversed and future deductions blocked however on 1 September 2020 Telkom changes the reference on the debit Order and deducts it again from my account... Surely this is deceptive behavior... They could not contact me for an explanation but could go and manually change the reference details so that the deduction can still be processed... I lodged a complaint on the app and to date have not received a satisfactory response just a reference number... You cannot get hold of them when you call you left on an endless waiting game that eats up all your airtime... Shame on you Telkom
