Service is very poor

2019 I took a contract of a router and sim with mobile talk underwritten by Telkom.I was not satisfied with the products I received, I requested Mobiletalk to terminate my contract with them. They requested back their 2 sim cards and router which I did send back the 10th of June 2019. Funny enough I still get debited by Telkom and yet I took the matter up with them to make them aware that i no longer have the sim cards and router therefore they should stop debiting my account.How do i send and make noise enough that Telkom you are damaging the status of my account my reputation as well, as I cannot afford to be debited for something I don't use or even have for that matter. I as given this reference number : ***3 someone called me and promised that they have cancelled the debit order from their side STILL NOTHING IS HAPPENING. THE SIM CARD NUMBERS : ***/ ***. Telkom is aware that I am not in possession of the sim cards but why are not still debiting my account. I was told that Telkom destroyed a whole lot of people's account reputation all because they insist on taking money from your account yet there is no reason for them to do it Please be informed that I am out happy with the strees that I have to go through every month to reverse payments from Telkom please do something. ACCOUNT NUMBER *** this is so unacceptable!!
