It seems my story has happen to many people. I was really excited to be switching to Sprint from ATT... but what a pain it is! I had everything ready to place my order but now I have to wait 60 days to be able to re-apply! I can't wait that long. Customer Service was of no help! It's so frustrating that you cannot prove your own identity! I have a valid US Passport, Driver License and pretty much all types of ID's! Maybe I should just stay in ATT!
Have you spoken with the manual credit review team at 800-639-6116? You didn't state if you were dealing with a store or telesales but manual credit review is the team that corrects things that aren't electronically correct, which is what your issue sounds like.
