Wells Fargo is jumping on the band wagon. My husband recently made a large pmt to his line of credit.
They immediately decreased his line of credit--"due to credit bureau based account management review." BS--with higher int rates and decreasing credit limits--the only thing lowering his score are the banks right now. According to WF--they don't have to give you notice--that comes in the mail after the fact. So be careful if you are doing the whole bal transfer deal--trying to get it all on one card w/lower locked-in int rate. Or if you use a balance transfer check.
They might yank that credit in the middle of all of it.
Also, according to the bank--they can do the same with your WF Business Line of Credit/MC. They can decrease it anytime--without prior notice--right in the middle of a transaction with one of your vendors.
