I called Chase today regarding our business cc card.  They said their new number for their business accounts was 800-472-0498.

I have rec'd calls from this number several times, with a totally different number to call back on with a 4 digit extension.
It's very annoying, especially if you have a Chase card.  You may think it is about someone using the card fraudulently.
I almost called it back today, because recently I had one of my credit cards compromised. There were 3 charges on my card that I did not make.  However, because I receive a lot of calls I do not recognize,  I Goggled this number first and discovered that it is a fraudulent call.

Got a call from this number and they said to call back and gave an extension number. My caller ID showed 407-771-0887. I looked into that number and saw several postings that indicated it was from a supposed Chase Bank located in Florida . Probably some annoying telemarketer
