Cannot cancel my Telkom Services - Worst customer service!!!

I have an account with Telkom for VOICE and INTERNET/DATA. The services were not working for sometime and i have been requesting Telkom to CANCEL the INTERNET/DATA SERVICES i have with them.

Overtime, due to lack of cancellation, the amount owing kept accumulating for services that were not working! They ended up taking me to their debt collection services (NuDebt). I was forced to pay up my account and since then, i have been requesting them to cancel my services, but they havent and do not respond to queries etc. This is the worst customer services that i have encountered in years and its so frustrating! I have tried logging queries via their support emails ( ********** ********** ********** and also tried calling to their support/billing numbers, chatting to their chat-bot system but to no avail!

This is ridiculous and frustrating! I am afraid, my account will continue accumulating funds albeit the fact that i settled the amount that was in question (which accumulated due to lack of action on Telkom side). I have been to their Cresta branch, only to be told that the branch doesn't have rights to cancellations but only customer-onboarding????? This is BS!!! I regret ever becoming their customer.

@Telkom, I need urgent assistance to this, else, i am going to make efforts to drag you guys to NCC or any effective regulator!!!!!
