Line not active yet

I received my new cellphone and requested a number port from my existing SP. I was told that the new line will be activated within 24 hours. After 24 hours the line has not been activated yet. I phoned the call center this morning, and their systems were down. I phoned again and waited 20 minutes without answer. I then called again this time holding for more than 30 minutes with no answer. Seriously, what's going on with their call centre? I really hope I do not have to wait days before my line is activated.
