Worst service and ****

I have two contracts with mtn one for home wifi router and one for Huawei Nova 11i, I have cancelled the home WiFi router since the contract ended in September i called MTN to cancel and also sent email I even sent inbox on Twitter but they keep deducting money last month they deducted R1600 now this month I have received an sms stating they will deduct R1000 I mean Where's this money coming from I was supposed to pay R300 for my huawei nova 11i since I canceled the Router, I will never recommend someone to join mtn, you're a **** Shame after everything and confirmation that the Router was cancelled but you keep on taking my money from my Bank worst part I'm no longer working that's why I cancelled the home Router account 💔💔😭😭
