Telkom

I went to Telkom on the 01/02/23 to sign up a data contract with my existing number, I was told the number needed to be ported, eventually the number was ported but now ℹ suddenly have 2 contracts with Telkom one on a prepaid number and one on a contract number and neither of them are operational but I have been billed for R500 for February The manager at Telkom Signet Terrace did all of this Mandy Swart. So if the head is *********** and uneducated who do i complain to?? Other branches are saying they cannot assist it has to be corrected by Mandy Swart and she is clueless. Who do I take this to
