most pathetic after service ever, no response, no assistance

This matter goes back to Dec 2017, I had a line using number ********** 641 which was used only for data, axxess was the ISP, I had the services cancelled through axxess this included the line as well, when cancelling the service and line, I even stated that ‘’are you sure you want to cancel the line? As this will remove the number from the service pool and it cannot be retrieved’’ I said yes as I have/had no intention of keeping the line due to moving residence and getting a fibre connection, after this was done, I kept getting bills each month for the number, even though it was cancelled, after a while I tried to contact Telkom for assistance, but have had no luck at all getting in touch with anyone via 10210, or the email addresses as it always said mail box was full, I eventually get hold of someone who tells me to email the request to ********** this was done in April, it stated that it could take 21 days for the request to be actioned, well 21 days ending up been months, again I tried to get assistance again I failed, finally get hold of someone ********** this was their reply in August

‘’Hi Roland, the ********** 641 was cancelled in 2017 and was replaced with the number that is currently active now *******, if somewhere on your account you still receiving bills on the old number, please send it on our email to ********** and please advised once invoice sent we will sent to IT as it may be an IT error as account shows cancelled.^CL’’

So that reply should mean that the service was cancelled in Dec, and that billing should not be taking place any further, but yet I am still getting billed for a service that has not been used since Nov/Dec 2017, I need to know why cannot I not get assistance from anyone I try and contact, why am I been billed for a service that is meant to be cancelled and what do I have to do to get this damn line cancelled once and for all? I will not accountable for any charges on this account due to the fact that I asked for this entire line to be cancelled by my ISP and yes they do offer that request and yes I have not used this service since the cancellation request was made in Oct/Nov 2017, I want this matter attended to on the highest of priorities and would like someone in senior management to get hold of me to discuss this matter as well as to get it resolved once and for all, it is approaching a year now that this matter has been going on and I can longer play the run around trying to sort it, when you call centers are virtually unreachable same goes for email departments, and please don’t get me started on the pathetic online service that you offer.

this is urgent and expect it to be treated as such.

Thank you
