2 month query

I have an existing lte contract which was upgraded to a 50gb package on 17 August for R699 pm. The store logged a query because the system automatically billed be the full price of R1499 pm. The case was closed by telkom a few days later with no correction. I again notified telkom and asked them to correct the bill. Still nothing was done and I was billed almost R2500 which I then reversed. I again notified telkom and yet again nothing was done, and they have once again billed me R1499. I have allowed the payment to go through as this should cover the correct outstanding amount, but your billing department has now suspended my account for an outstanding balance which is not due to telkom. Your service is ****** ridiculous, for 2 months 3 queries have been logged and no one cares to correct it. I am going to report telkom to icasa in terms of the CPA and treating customers fairly as I have now paid for the service which you have suspended. The service is appalling, and your poor staff at the call centre can only but continue to log queries which is of no help because billing has no contact number and no email address. COMPLETELY APPALLED BY SERVICE!!!!
