CELL C - BAD SERVICE & ***********

I am eligible for an upgrade and halfway through my upgrade process on the 11th of September 2023 at a store. The store computer system prompt "Legal" and my upgrade was halted. I was told that there was a long outstanding balance of R748.00 and I should pay immediately to qualify again for the upgrade. I immediately paid through the Cell C app via payfast card payment. To date, I have attempted numerous times to follow up via e-mails and calls. The system has not been updated and the monies paid had been receipted to my current account and now sits with a credit balance. The R748 should have been allocated to the correct account in order to update my profile on the system. I am highly upset , firstly that I am long serving client of Cell C and I am on automatic debit order , so there should have not been an outstanding balance in the first place. Its the 21st of Sept and for some reason Cell C just cannot allocate my payment and clear the error massage. Highly disappointed with the level of service and incompetence shown.
