Three weeks and my phone hasnt been activated

I finished my contract with cell C and took out a vodacom contract three weeks ago. I received my new phone but they haven't been able to activate my phone. My number had to be archived which they said takes 24 to 48hrs but on Tuesday it has been three weeks. I find this unacceptable and I am regretting moving from Cell C. I have wasted time and money phoning on a daily basis and no one can give me any answers.
