Bad service from vodacom

I have a complaint. I app**** for a new contract the 2 Dec and application was approved. After phoning them the 13 Dec to find out where my application is in process they told me that the contract I app**** for is no longer available. They never phoned me that the contract I app**** for is no longer available. The lady that I spoke to told me that se will speak to my superior about my application and phone me back on the 14 Dec which also never happened. This was suppose to be a present for my fiance on the 16th which he will not receive due to there bad service.
