Bad Telkom Service

Hello Mr Peter. Telkom really failed at keeping their client's happy. I called them last week Monday for a sim swap on one of my contract number and they promised to call me back and finalize the request but nothing. I followed up with them on Wednesday and they said matter has been escalated, on Friday I followed up again and nothing has been done, I have been dealing with a lady by a name of Simlindile and she hanged up on me today after she told me that the request is referred to here manager. Please help me to ge the request finalised, surely can't wait to end contract period and cancel this bad service from Telkom.
