BAD SERVICE

I have been receiving calls from you since last year for the account sold to you by Tracker. The first time I received a call I was told that my balance is R753.27, I then made an arrangement to pay R200 monthly until the account is settled. On the 2nd June 2020 I made my first payment using the reference number I was given which is ***. After a week or so I the received another call telling me that my balance is still R753.27, meaning the R200 I paid never got adjusted. I even sent a proof of payment to *** , *** and also uploaded it to the tracker whats app account but no one is adjusting the balance. I receive call every week asking when am I paying the R753.27, I am tired of explaining the same thing over and over again,
