Pathetic Service

Went into a Telkom Store to cancel my data contract due to such poor coverage.Got a call 30 days later from an agent who tried to give me an alternative to cancelling the contracy. She promised me that a technician would be sent out to assist with coverage within 72 hours. No one came or called. Got a call a week later from the same person with the same promise and yet again nothing. Logged a comment on twitter and was promised that someone would call and again nothing. I am appauled at the service delivery that a large company would offer. That is why everyone is leaving. I am so disgusted that I dont know what to do!
