Service delivery issues

I am SO annoyed with Telkom mobile service. I called to cancel my contracts last Friday June 18th, the agent gave excellent service, and I decided to go with the month-to-month package instead of canceling.... Ever since, my caller ID is not working, and ALL calls are showing as unknown on all my numbers... Saturday 19th I called Telkom to ask why this is happening. The gentleman said that he would raise a case number and it will take 3 days to resolve... It's almost day 7 and still no feedback from telkom. The sms I was told I would receive never came... In the meanwhile, my calls are still coming through as unknown... Frustrating!!! Called Telkom again, the case is not resolved, no movement has happened... it will take 72 hours to be resolved... Like what the heck, your service level agreement of 3 days has already passed... I must wait another 72hours?? not a chance I want this issue resolved please. At least send communication to let me know what's going on...
