Accounts dispute STILL NOT resolved

I filled in a cancellation form for my fixed land line on 21 December 2017 because the premise we were moving to had no infrastructure for a physical line. The form was filled in and signed at a Telkom shop in Higjveld Mall whilst I was taking out a 40+40gb LTE deal at the time.

Fast forward to 23 October 2018 when my wife and I place pre-orders for the new Huawei Mate 20 Pro through Telkom. My wife's request is handled swiftly and mine on the other hand never went through because apparently my account with Telkom for my physical line has been suspended due to me not paying for a line I cancelled almost a year ago.

I phoned the call centre and then the opened a dispute against the outstanding money because I resent my original cancellation forms WITH Telkom's official reply that stated the line will be cancelled in 21 days.

The dispute was opened on 26 October 2018 and I am still awaiting someone to phone me regarding my dispute. It has been escalated twice and the line has been cancelled in the mean time but without the dispute being cleared I CANNOT get a ****** cellphone contract through Telkom because of THEIR mistake they made.

Please can somebody just take 5 minutes out of their day and clear this up??
