Telkom Worst Service Provider

Telkom is the pits. I went to their stores in Walmer Park and spoke to some lady. She advised me my contract upgrade can't be done because of some investigation. Fine. I go home. Next morning I receive an email telling me about my successful upgrade and the billing for the coming month. I tried caring the 10213 number and stayed on the line for more than 60mins with no help. This was from Monday till Today. No one answers. I tried calling the store, no answer!!! I called the call center number 180 and speak to Zintle Ntetha whom I ask to speak to her manager but she tells me the manager is on an escalation.?!! Surely there's more than one manager in that call center. After 50min I eventually speak to her team Leader Lungi Cele who is of no help and refers me to call this 10213 number after I told her no one answers. I'm sick and tired of Telkom and want my contact cancelled immediately!!!
