8ta (Telkom) - Deducting Funds after Cancellation

I cancelled my 8ta (Telkom) contract in early February 2016 and received confirmation from [Email Removed] that they acknowledge my request and that my contract had been cancelled. <br> <br> They further advised that the notice period is 21 working days and therefore the full amount of my contract would be debited at the end of February and a pro rata amount at the end of March. At the end of March, the full contract amount was deducted from my account and I have subsequently tried numerous times to email, call and used the online chat service to obtain confirmation that this was done in error and that no further funds will be deducted from my account. <br> <br> I have had no response via email, I have been unable to reach anyone on their customer service line (even tried calling stores all around South Africa in an attempt to try speak to someone who can help - no one answers). The online chat is useless and resets perpetually, so even when copying and pasting my frustrations repeatedly, it is ignored until it resets, leaving the issue unresolved.<br> <br> I would greatly appreciate a response from 8ta (Telkom) confirming that they will not deduct any further amounts off my account!
