Pathetic from Telkom Mobile!!!

I had 2 Telkom Mobile accounts a few years ago, i paid both of them up in 10/2017, to date Telkom has not updated my ITC, i requested paid up letters 6 times, i spoke with different managers, Paul, Sicelo, both advised they will escalate however still...NOTHING. Everytime i call their call centre, the agents says your account is settled and paid in full, they say they will send me a paid up letter but it takes 7 days, when i asked them and management can this not be done sooner, im told point blank no, im told its a back office department and that they dont take calls and that there is no manager in that department that i can talk to. PATHETIC from Telkom, since 2017 they could not get this done? who works there? is anyone doing their job? this is a JOKE
