KEEP BILLING A CANCELLED LINE

I'm not sure how to tackle this anymore...I have been trying in vain to cancel a line that have been migrated to anther service provider in August. What the hell are you doing????<br> <br> I have reference numbers as long as my arm..<br> <br> Alice van der Merwe confirmed that my contract was cancelled on 12 Nov 2015 and I still got a freakin debit order this week. Ref *** And your portability number doesn't exist anymore so I cannot call again. <br> <br> Lebo at this 'no longer existing' department confirmed on 13.11.2015 at 10.20am also that my contract was cancelled and that I could expect a refund in 10 days. This didn't happen. Ref ***.<br> <br> Various visits to your 2 branches in Brooklyn Shopping centre were a total waste of time.<br> <br> You don't have permission to take my money. Can this be regarded as theft? <br> <br> I BEG YOU TO CANCEL MY ACCOUNT!!! WHAT MUST I DO???<br> <br>
