Telkom reap off

I'm a principal at a high school in Soweto. In June 2020 I had to use my Identity document for the school to get internet account with Telkom. Later on that month I was offered a mobile contract from the same company. The mobile contract was not supposed to be linked to the school account for auditing purposes. The initial mobile contract was supposed to be R165 monthly but I found out that my bank account was debited R199 and I was also being billed R205 from the school's invoice. In September I went to Telkom Maponya to lodge my complain and I was told that my problem is under investigation. They told that I will receive an SMS as soon as the problem is resolved. In October the service was disconnected due to the R205 that was unpaid, when I called the customer service I was told to pay that amount for the account to be activated and that the two accounts will be separated. Today I called the customer service to be told the same story, I spoke to a customer consultant called Ethan who told me the same story. I then asked him to connect me to his manager but he told me that he is working from home but will send communication for his manager to call me back. Until now I haven't received any call. Kindly help because I feel that I am being reaped off, I am paying more than double the initial agreement. This is denying my credit record.

Kind regards Eva Skosana
