Number porting

I took out a contract two weeks back and specifically asked that my old number be ported. The call centre sales lady came back almost immediately and old me that they have a problem with the porting and that as soon as I get my new phone I can go to any Telkom branch for port. I did that and was told it will take about 72 hrs for a successful porting. I waited and nothing hap pend. I wnet back the did it again and waited another 72 hrs and still nothing happened. Called their call centre and they advised me that the 2 prevoius occassions it failed. they asked me to send a message to Telkom and they will do it. I have sent it but nothing has happened. I am now going around carrying two phone and this is an inconvinience for me. I really need this nuber ported.
