Incompetence in the MTN accounts department

I am very unhappy with the service I am receiving from the mtn call centre and legal department.

If you phone the call centre their is a 2hour waiting time to speak to a service champion.Is this acceptable? Then I moved bank accounts from FNB to Discovery bank,tried making a direct payment to your ABSA account which was given to me by a service champion just to be rejected by the bank as invalid.No one phoned me from MTN to find out why they aren’t receiving payment from me,instead they just block my account.By blocking my account I can’t receive OTP’s to make a payment through new app.This up and down happened in May 2020.I was told that I still owe R200 on my account.They then gave me a FNB account in which to pay the R200 to open my services again.I did that on the 30th of May 2020.They then opened my services again when the debit order came on the 2nd of June they tried to deduct the R200 again.I then after a month managed to get my banking details changed they then notified me that the R200 is still outstanding.I have sent the proof of payment a month ago to the service champion called Moses,sent it again yesterday to your collection department.I am due for an upgrade on one of my numbers.When i got to your store this morning I was told that my account is blocked by Legal and that a can’t do the upgrade.I am being penalized for incompetence in your accounts department.To make it worse your call centre/legal collections is not working on Saturday’s.
