I am pleased that someone at Globespan realised that you were disadvantaged by the telephone number.
It sounds to me as if they have been reasonable in offering the ability to change today, even though that is not what you need.
As for Groundbum, I'd give up; s/he obviously has little comprehension of contract law and prefers to cast aspersions and personal insults - not worth the time bothering with.
