The last thing you want is for Rats to eye your account. This never leads to good outcomes. And you don't want to banned by Chase.

I would agree that not calling is in your best interest. I would also moderate your GC purchases for the time being and use the business card for other business related purchases.

Chase is a big player in the CC market and being banned by them does put limitations on MSing activity.
