Telkom account cancellation - The Worst demon

Its been almost 1 year 8 months, sending the emails post to pillar ( case numbers : ********** 7; ********** 2; ********** 1; ********** 6; ********** 1) with cancellation documentation request but to no avail. My bank account is being debited twice a month for the mobile data which I am not receiving. How is it possible for a company like Telkom to request a customer to send the cancellation documentation when the contract lapses? The common sense is all the billing system should expire if the contract lapses. It really tells they have poor or no standard business/programming systems in place. The Retail Ombudsman needs to be alerted about this bad practice and I do not think the is IT Auditing at Telkom.

Telkom is really a *******.
