unauthorised debit of my account

Telkom is possibly the worst company I have ever dealt with. I have an Ipad with them and in July my account was debited but it bounced back. Then end of August my account was debited by R1077 for July and August and I paid the rejection fee and that went through. Then my account was debited in September as well and that also went through. Ever since then an amount of R115 went off my account 5 times for a failed debit order of Telkom. Even to this day it still goes off my account and my Telkom account is up to date and I am in the process of cancelling. I call Telkom they say its my bank, I call my bank they say its Telkom. I don't care who it is I just want my money back. I tried calling Telkom but as always they are not picking up and if they do they refuse to put you through to a manager or team leader. I also went to a Telkom branch but they are useless as well.

This is the worst display of customer service i have ever seen. I didn't even have to tell my friends to switch service providers cause they also got the same disgusting service I got. How this company is still in existence is beyond me
