Did you shop at Target about the time they were hacked? Maybe you’re blocked. I’d definitely check at the bank regarding your issue. I checked to see if I needed to change mine and was told I’m ok as didn’t purchase during that time with my card. Also Target gave them a list of who was compromised. I used my card an hour or so ago, no problem. Definitely check it out. I have 2 friends who received new credit and debit cards from Chase without asking, with letter explaining why.
