New contract and Sim swap

I went to Telkom to take out a new contract they told me they don't have phones in stock and will let me know as soon as they get phones. It has been more then a week know and nothing. I also did a sim swap on the same day I paid for that but until today the number did not change. If I phone the client service department they only say that they can't help me I have to go back to the store. If I phone the number for the store at the Vaal mall it rings and go to voice mail.
