Experian can be a little funny. You are in a time crunch so here are your options:
a) Go online to experian.com and file the dispute online,
b) Keep calling every day until you get a human,
c) write a dispute letter, attach a copy of the drivers license, ss card, copy of utility bill or cc bill showing name and address as proof of identity (total of 3 items). Mail certified return receipt delivery. They have 30 days to respond upon receipt. Usually only takes 2-3 weeks though (I know this because I have a credit repair business and do this every day).
Wishing you the best outcome!
