Bally's is a PITA. I remember 2 years ago when we were doing our mortgage and DF had Bally's on her CRs. Our mortgage processor was like "Don't even worry about Bally's - everyone has that on their report. Even I do." lol
We are trying to get it off now and reportedly Bally's has called it back from the CA and it should drop from her CR. It was on her report because they didn't close the account when she moved (and showed documentation that there was no Bally in 30 miles)
Anyway, if you want to actually talk to them the phone number is 562-484-2000 x0 and ask to speak to someone about your account. Then maybe try a PFD. You can also try to mail a PFD.
