CUSTOMER SERVICE FROM TELKOM IS EXTREMELY POOR

Telkom has not resolved my currently situation of them double charming me with the Wi-Fi that was cancelled i have then followed up with them but with no response. Now they have handed over the account messing up with my credit score. Please advise of where I report this further because now, they are ****ing up my name. I THINK I SHOULD TAKE THIS MATTER TO OMBUDSMAN THAT IS WHEN T5HEY WILL RESPOND AND TAKE THIS MATTER SERIOUSLY
