MTN pathetic service

I app**** for a black friday deal. I was approved. I then stated to the lady I need to keep my current number I dont want a new number. She then stated that is fine I will get the new sim card and then I can go to a mtn store and they will make it use my old number. Just called to follow up on the progress of the order and I then stated again I need to keep my current number. The new lady then stated if you did not do it at point of sales you wont be able to keep your old number. I was now forced to cancel everything and when asked can I now have this number on the contract and they refused and said no. I need to apply again but the black friday deal is finished so they cant help me! This is truly **** customer service you can play back the recording I clearly stated several times I need to keep this number. Can this be resolved or do I just get a contract with vodacom again? If this is the service I think it might be wise to stay with vodacom.
