Terrible after sales service (porting of number)

What a terrible post sale experience. I took out a new contract with Telkom. I explicitly asked the sales consultant if my existing prepaid number can be ported to the new contract number. He assured me that is was no problem I should just go to a Telkom store as soon as I receive my device and new sim and they will happily assist. What a nightmare it has been ever since. Went to 3 different Telkom stores, none of which can help me and every single one with a different story. Spoke to numerous consultants at Telkom customer care, all of which also have a different story. Cancelling my contract now.
