New contract, still no phone

I left a different network provider and decided to join MTN. I went to the MTN store in cascades 2 weeks before my previous contract expired. Explained to the manager the phone i want and asked him the procedure. He assured me i can come to the shop on the 1st of Feb and it will all be sorted out in 2 days max. I informed the consultant that i dont want to be without a phone for too long. He reassured me again. Firstly i went on the 1st and my application was only approved on the 4th. After i had to contact MTN numerous times to find out when my contract will be aproved. On the 4th i went to the shop to collect my phone as i want the Sony Z5 compact in white. Then they said they dont have stock. I told them that i had ordered it a while ago and there have already been so many delays. The consultant assured me that she will source the phone for me and get back to me before the end of the 4th. At 4pm i still have not had any feedback, when i called the shop the consultant responded: \oh yea, we can only get black phones\" . My problem is that there is no urgency to help a new customer, which left the competition to join MTN and after 3 weeks i still dont have a phone."
