I, too, received a call from this company yesterday.  I'm somewhat gratified to read the posts of others who got this too, as I was concerned that maybe I'd unwittingly given out my bank information to this company in some way by mistake.  I'm not that computer literate and it would be just like me to make a mistake.  Anyway, they told me that they had my bank information and that I'd spoken to someone last week and asked them to call me back.  They were about to take a deduction for this medical card.  When I objected and said I already HAD medical insurance and had NEVER given my bank details out OR asked anyone to call me back, she told me she would give me a refund number so that I could get my money back.  When I asked for the number they hung up.  I immediately called my bank and told them not to allow anyone to make any deductions for any medical cards as I thought I might have been scammed/had my identity stolen.  I also ran all of my credit reports just to be on the safe side.  Funnily enough this scam artist had trouble understanding ME.  I have a very strong British accent and I guess it was too much for her as she had to keep asking me to repeat myself.  Eventually, she lost patience and just hung up. LOL!
