Telkom failing to close my account

<p>I closed my Telkom landline-ADSL account in December 2015. Ever since that time Telkom keep submitting debit orders against my (frozen) account. I do not make provision, so the debit orders are sent back and penalties are incurred every time. I went to Telkom, Menlyn THREE times, queueing for quite a long time, every time. On 5 May I received an sms stating that Dispute no. ***5 had been logged and that R1530.04 would be credited on my next account. And shortly after that, yet another debit order was presented to my bank account. I cannot seem to solve this problem.</p>
