Bad service

Hi.I took out a contract with Telkom mobile did a port in with my manager number on the 21 December 2015. The port in went through but the number doesn't work. On 31 Dec I called in and they confirmed that it will be sorted but wasn't. When you call the man number it says it's not available. Today is the 3rd week waiting for this to be sorted. I have been calling and coming in store trying to fix it but with no luck. This morning one of the consultants promised that it will be sorted by end of business. It's now17:41 with no call back or issues resolved. I'm frus treated and irritated with this. Telkom seems not to care about this. They don't take their client seriously. I want to cancel this and go back to mthe.
