Porting of number

I cancelled a contract with telkom due to their ineffiency and poor service. I then requested for my number to be ported to mtn on 1/3/2016 and to date it has not been done. I have been without communication, unable to make or receive calls since taking this contract with Telkom. I have had to endure going to the midlands liberty mall on several occasions even discussing this matter with the store manager who had reassured me the matter would Be sorted in 2 hours and that was at 11:30 today. and I am still waiting. A service should not be offered if it cannot be provided. Irritated, unhappy and disgusted. I want my number back asap!!!
