Lost instant buy verification @ Coinbase/ how do I get it back?

[RobB]

I recently made a purchase that was reversed due to insufficient funds and my verified CC was removed from my account. I got the account re-activated (had to purchase the amount of BTC that was cancelled) and am trying to re-verify my card but it won't accept it now, I get this message ""This credit card
cannot be added. Please contact support.".  I had contacted support on the 30th and so far all they've done is reply to confirm that the card was a Visa.

Has anybody else had the same problem?  Any ideas of what to do?  Thanks!
