Do NOT Give out your credit or debit card #s OR checking# to ANY phone calls (unless you are the one who called)
Per a comment at another website -  that said this # was from IFCJ
-IF- this is from International Fellowship of Christians -  they aren't leaving a voice mail.
I do give to this ministry so their calls are ok - I still don't answer.

Because whomever calls - does Not leave a Voice Mail -  AND because I can't find 708-730-4400 on their website - I think this # is a scam. -  This 708# is listed in Calamet, IL

AND if anyone receives ANY call from Anyone do NOT EVER give your credit or debit card #s or checking acct #s over the phone.
So if I was you, I would simply not answer and report the #.
