It is a legitimate WFB number, but it can be spoofed.
If in doubt call a WFB branch home loan specialist, and verify the caller the call buck number and reference they gave, the genuine WFB people understand and will appreciate your security.
If you haven't got a home loan re-fi in place with WFB they shouldn't be calling from this number.
Caller just called, I didn't know the number, so I didn't answer. I have been getting a lot of calls from debt collectors but I don't owe because I don't charge, etc., This caller left a message, a stumble bum message, that he said (asian male voice) call us back and reference this number so we stop calling you. What?
