96 Hours and still no activation

I took out a contract with MTN over 96hours ago and had my number ported from vodacom, i was told the port would happen in 24hours which it did but 96hours later and i am still sitting with no network because they have yet to activate my number. Every time i call they tell me wait 30 more minutes or wait another hour. Then i get told to call the port department myself and request for the number to be activated. When i did that they now tell me the port can only happen tonight??? Vodacom did my port with in 30mins and there was no waiting till after a certain time. I have just received this contract and i am already fighting for them to delivered service i am paying for. I want this contract cancelled and they can take their phone back i refuse to fight for service and to fight to be on a network that is refusing to do their job and help me!
