Service provider cannot activate my number

I have upgraded my contract through celldirect and I have received the new phone however they have not been able to activate my number. I was informed that I should call them as soon as I get the package and I have been doing it since last week last week Tuesday. Every time I call them they say it will be active between 2 and 72 hours. I have been calling them everyday since I got the phone with no luck. This CellDirect company have a tendency of undermining customers by lying for the most of the time. They make empty promises everyday. I regret myself for having accepted their service at first place.
