Money still being debited -cancelled 5 months ago

My internet-5 promo expired in November 2013. I continued utilizing the contract on a month to month contract. <br> <br> On 7 December 2015, I visited the Telkom Bayside Branch to cancel the subscription. I completed the cancellation form and received a case number.<br> The last debit order should have been at the end of January 2016.<br> <br> A debit order was still deducted off my account at the end of February. I went into the Tygervalley Branch on 21 March to query this, and the consultant said that the request had not been processed properly. She put through another request and asked them to expedite it.<br> <br> I then stopped the debit order through my online banking profile and reversed the debit from end of February.<br> <br> This morning, another debit order passed through my account for 3times the monthly subscription amount.<br> <br> This contract is expired! The notice period was given and yet I'm still be charged for something I'm not using!<br> <br> I have left messages via your website, and no one has contacted me. Yet I received constant phone calls from your sales department wanting to sell me a new contract. <br> <br> Please can someone who is competant enough sort this issue out.
