Continued to be billed after submitting cancellation in November 2017

I cancelled my Telkom service on 29 November 2017 and was informed that I was to give one months notice and that I would be billed for December 2017, which I was happy with. December came and I received my invoice and made my payment so that I was fully settled up.

Then January came and I (incorrectly) received an invoice for January 2018. I immediately followed up with accounts and I was informed that my cancellation had not been processed. I was asked to email all the relevant documents to the lady in accounts email and I did so. I did not receive a reply or any further correspondence. I have now received a bill for February. I have not resided in the location I am being billed for, for 2 months so I am clearly not using the service and I followed the procedures that I was instructed to follow, yet I am still being billed.

I have proof of my submission of the cancellation forms and necessary documentation as well as proof of payment of my final bill and all follow up correspondence via email. I refuse to pay this account and demand that someone from Telkom sort this out as this is the most appalling customer service I have experienced to date.
