Account Cancellation

I cancelled my Telkom account in November 2014 as we were moving home. Confirmation of Cancellation was received via sms. Despite the confirmation of cancellation I have been receiving sms's to urgently pay my arrear account. On each an every occasion I personally went to a Telkom shop to AGAIN remind them that the account had been cancelled. Emails were sent internally advising of the cancellation and requesting my account to be backdated. Despite all of this I have now been handed over by Telkom for non-payment of an account that was cancelled in 2014!!! Come on Telkom, get your house in order!!!. This is not a way to treat your customers!
