I wrote a cash advance check for {$5000.00} in a cc with {$11000.00} available credit. Although I was not notified, and contrary to the same bank previous practices in another cash advance check I used in XX/XX/XXXX, this time Bank of America ( the card issuer ) eliminated the " grace period '' in all purchases charged to the card! So that, although I kept paying my purchases in full as before within the ( now ) grace period and keep the end-of-the-month balance below the {$5000.00} ( spent on the cash advance I was supposed to have to pay by XXXX XXXX, I am now being charged interest on any purchase on the card. Basically they changed the card terms besides the credit they provided relative to the cash advance. They surreptitiously eliminated the 'grace period ' that had always been applied to all non-cash-advance card purchases and starting charging me interest even when the non-cash-advance card balance was paid in full within the customary grace period I never thought would be affected by me accepting the crad ' cash advance offer, for which I provided due consideration in the form of a cash-advance fee of about 4 % on the {$5000.00} cash-advance.
