Account cancelled but still getting billed

My telkom mobile contract was in month 24 and I visited the branch in Pavilion to ensure that the contract gets cancelled as I chose not to upgrade with Telkom and at the same time requested that telkom home line be cancelled as I relocated from JHB to KZN. My account was debited from the end of Jan 2015 till March 2015 until I visited the bank and put a stop on the debit order. The next day my mobile line was suspended despite asking to stay on the same number as a prepaid customer and I received a message stating that my account will be handed over to lawyers if not paid. I have received an invoice for April 2015 which amounts to over R300<br> <br> What are the staff doing at Telkom. I had to visit the Overport Branch 3 times to get this corrected but to date there has been no feedback. I even went as far as completing a dispute form as Telkom is owing me money for the months my account was debited after cancelling.<br> <br> Had I not stopped the debit order looks as though I would have been ****** of money from my account for a service which is no longer in use. <br> <br> Furthermore this creates a negative impact on my credit rating which I find unacceptable.
