payment made

I have logged a complaint with telkom on the 1st of december 2020 regarding a cellphone contract I have with them. the network provider claiming payment has not been made yet proof of payment is available proving that payment was indeed made I have been communicating with telkom customer care and finance regarding this so that it may be resolved as soon as possible yet to the day an entire month later the matter has still not been resolved to an extent that telkom has even interrupted my service. I still get messages from the network provider that payment has not been made and my main concern is that this could lead to unfair black listing and a bad credit profile. The network has not hesitated to cancel my service they do not delay in sending me daily messages of payment not made yet they have not been as fast to respond to all my emails and calls regarding my case (***9) that payment has been made to them and that they should clear my name. This is beyond ridiculous and unacceptable. It is frustrating to say the least
