Telkom!!!!

In 2018 I sold my house and moved abroad. I tried to cancel my my Telkom service in May 2018 and was told I can only do so at the end of June 2018. I then cancelled my service by handing in my firms at a Telekom branch. The branch accepted the forms. When I called telkom to confirm that they had received my forms, I was advised that I had to cancel online. Which I then did. Telkom kept my account active for 2 more months after that and have been trying to get the money from me ever since. I have called Telkom from abroad. I have sent friends on my behalf to Telkom. I have emailed documents to them and been advised 2 years ago that this was settled. I am now receiving threatening texts on a mobile phone still registered in SA, from an attorney demanding payment !!!! Come on Telkom!!! Get your act together.
