card.com

I received a debit card in the mail from a bank I've never heard of I recently received a debit card in the mail, associated with an account at a bank I don't use (and in fact have never heard of). My credit is frozen with the big 3, but apparently to open a debit/savings/checking type account, no credit check is required? Lovely. The bank is card.com / pathward bank, and they have an abysmal BBB rating (the best info I've been able to turn up while googling). Tons of similar reports of "Bank opened fraudulent account" type reports there. I also googled them and called two different phone #s from websites (which happen to match the info in the paperwork I received, but I didn't trust that until verified of course). Their phone system starts out by requesting your zip code and *full, 9-digit SSN.* There is no way I'm giving them that information, but as a result I'm unable to speak to anyone at the bank. It makes the whole thing smell like the bank itself is phishing for SSNs associated with names/addresses. Sketchy. What's the right course of action for me at this point? I've had past issues with Identity Theft, in the form of a fraudulent unemployment claim last year, so my information is certainly out there somewhere (thanks constant corporate data leaks). Any help or suggestions to get this shut down will be most appreciated :)
