Blacklisted because TELKOM DIDNT STOP INVOICING ME EVEN AFTER MY SERVICE WAS CANCELLED.

I cancelled my Telkom line in 2019 of which I have proof of. I even went into the store to spoke to a consultant. I was billed all this time and now Telkom has blacklisted me, I want this rectified and the fools who didn't do their job to make sure it gets handled.
