Early adopter pains?

Okay a better title probably should have been my struggles with T-Mobile since last Friday, but in fairness to them I am going to give them a chance. The problem since Friday has been repeated all circuits are busy errors on our phones. I say all because we have a total of 5 lines with them. Yes we pay a small fortune as 2 of them have full service including BlackBerry Enterprise. The phone staff has been courteous and I have now filed 2 trouble tickets with them. Last nights tech stated to me "well it sounds like we just don't have capacity" and this really got me going. What do I pay for? Is T-Mobile really at capacity here in Bend? Wouldn't you think that they may have seen this coming in one of the fastest growing cities in Oregon? Okay my rant is done for now...
