Better Check On Your Signature Card

I have opened 12 CD accounts with Discover over the past 2 years.  Each one requires a signature be mailed back.  The first 11--no problem.  Today I noticed a debit on my most recent CD.  I called and was told they never received the signature card so I am subject to backup withholding.  I explained that I mailed the signature card back the same day I received it and reminded the CSR that I have had multiple accounts showing that I am not subject to backup withholding.  It was like talking to a brick.

Bottom line--they may have decent rates but if you open a new account make sure to double-check that the signature card got back to them. 

Very disappointing...
