I originally made the mistake of linking the CC and Checking acct's befoe I got my debit card and like many others got locked out as it wants the Checking Acct # as a security block.
I ended up just creating a new account for my Credit Card and it worked fine. I didn't bother calling and trying to have them unlink as in my experience anytime a CSR starts messing around with your account bad things happen.
It has also been about 7 business days since opening my checking account and still no debit card in sight.
If it doesn't arrive tomorrow I am going to call and them overnight it.
