Bad bad service ! ****mers! And *********** people!

I paid up my MTN account a few weeks ago an amount of R35050 and I spoke to Samkelo who assured me that they have Recieved the amount that I paid and will request for a paid up letter. I called in and I spoke to him team leader Ayanda who promised me that he has escalated and will send the paid up letter and he didn’t. I’ve been sending emails to both of them but they are ignoring my emails !! I did a follow up on WhatsApp and was told I’m owing another R10000 which I didn’t know where it came from,took screenshots and sent it to Ayanda the team leader and never bothered to respond to me. I phone in again now and spoke to a lady who was honest enough to tell me that there was no escalation that was done by Samkelo or Ayanda therefore I won’t be getting any paid up letter because it wasn’t requested at all according to what she can see on the system. I requested to speak to a manager he’s name is Sithembiso and he said he can see that I paid off my MTN account but on the MTN system my account is still billing!!! How is that possible ??!! These people are ****ming us ! They don’t know their job ! When I was still owing I was getting calls and emails from them daily ! Non stop!! But now that the tables have turned I’m getting ZERO assistance instead they make empty promises! I’m so angry because if it was a white person they would’ve gotten better service than hat this Bull**** service that I’m getting from them.
