Same thing just now. Not sure who it is.

I just got a message from this number saying your balance fell to -156$ as of 2/3/2014 and to please contact them immediately I looked up the number before calling and it says it is sigmah nursing home and pharmacy in Houston texas and I tried to call the number back and it asks me for my card number what card number? I didn't put anything in and hung up the phone because it was an automated machine and said was never going to put me through to an actual person so watch out!!!
