INFURIATED WITH TELKOM SERVICE

Incompetence from both the sales team call centre, technical team and the accounts team. I recently app**** for fibre services which was valued at R807 per month with a 3 G mobile card. Firstly since September no has been able to figure out why the sim card does not work hence no access to the data. Next i get bill R4174 for a service that is supposed to cost me R807 per month and still no one can explain what the hell is going own. Now i am R3200 in the red because some could not do his job properly after spending more than 3 hrs on the phone trying to get the problem resolved. Even going to the telkom shops does not even help. the call centre agents sometimes just put the phone down on you without notice and they don,t even bother to call back. Now i am at a LOSS AND I DONT KNOW WHERE TO GO NEXT TO GET MY PROBLEM RESOLVED. SOMEONE PLEASE HELP
