Hey Guys,
So, Nationwide has a number where customer care reps IMO are much more professional. (866) 889-9179
Also, they have a recon/dispute fax number for GW and recon letters. (516) 576-0422
They also have an address you can submit recon/disputes to:
Card Services
P.O. Box 9215
Old Bethpage, NY 11804
Just thought I'd share this with you since I just weaseled it out of a credit analyst in their department who refused to increase my limit. We'll see what happens.
