To port or not to port. That is the problem.

On the 1st of April I moved my mobile contract from my current service provider to Telkom mobile. I did this because of the free whatsapp and mobile data offered by Telkom. I asked the sales representative if I can port my number at a later stage as I still had airtime in credit with the previous network provider. He ensured me that I can move my number anytime. I only need to come to the outlet or contact the customer service call centre. Unfortunately I have not been able to use this offer yet as Telkom still has not been able to port my number from the previous provider. This after I contacted the help line and even went back a second time to the outlet to request this. So I now feel that I have been ******. I have this state of the art handset with data but I cannot use it because the number is not mine.
