Mike,
I have always had bad luck with Sprint via the internet, but there customer service telephone people have been fantastic. I switched my long distance to SPrint several months ago after horrible expereince with another carrier - including 30 - 45 minutes telephone holdi times with their customer service. Sprint has responded quickly, apologised if I was on hold more than a couple of minutes, and fixed any problems promptly and courtesously.
Try calling them.
Larry
