Telkom won't cancel debit order

We cancelled our 8ta contract at the end of November last year (24 month contract). Cancellation was done at store - we have the paperwork to prove it. We have not used this service since 31 December 2014<br> <br> 26 Jan debit order erroreously went through R199 - we reversed the debit order<br> 14 Feb debit order erroneously went through R398 - we reversed the debit order and went back to the store. They said they already had a record of cancellation - opened a new case number ***0. <br> 21 March we received an SMS saying case number ***0 was closed.<br> 27 March we were contacted by nuDebt, who claimed we were in breach of contract. I spoke to someone called Kemenshen and sent the original paperwork. He said the proof we sent was fine they would notify Telkom and there would be no more problems.<br> <br> 14 August - debit order of R1194 went through<br> <br> We have now reversed this and closed our bank account - it seemed that there was no other way. However we still don't know when this issue may pop up again. <br> <br>
