Disgusting service

In August 2018 I put in a request to Telkom to have my services canceled with them from end of September, I could only do this online which I did, I have since then been receiving invoice for services I no longer use. Their response for this is that they are waiting for Mweb to place my line into a holding pool which was done on 29 September 2018 with reference: ********** 36A. I was then advised by an agent to send her an email with all the details which was done on 16 October 2018, and no response since then has been received, although I have received yet another invoice, the service received by Telkom is absolutely atrocious.
