Unable to port number

took up a new contract with Telkom Mobile and picked up the device on Sunday 20/03/2016. I opted to keep my existing number and was advised that the number port would take place on Tuesday 22/03/2016. Recieved a call from the store in order to do the porting, they advised that a pin is sent via sms to the number which is to be ported however no such sms was coming through. After a least 5 attempts with me calling the store each time to try to get this done they finally figured out that their system was down. Called the store again on 23/03/2016 and had the same problem. Called telkom call centre where i was informed that a mail needed to be sent from the store to back office in order to bypass the pin requirement for porting to occur. Called the store once again to inform them of this and they stated that have requested a technician to come through to find the problem. Called the store once again in the afternoon and they advised that they have sent an email to back office and will provide feedback today 24/03/2016. Called the store a number of times but there is no answer today. I fail to understand why porting my number is met with such great difficulty. Assistance needed.
