Someone claiming to be from Dwolla just called me to "verify details of my account" from a 515-422-xxxx number. They wanted me to give my name and address. I declined and said I don't know who you really are. I've never done a single deposit to them, only withdrawls from Mt Gox and TradeHill.
They may be quiet on this issue, but they're doing something to cover their ass now.
515 is a Des Moines, Iowa area code. Thats where they are located. They called me yesterday as well to ask if i was happy with the service and if I had any questions. I had to cut him short because I was at work and couldn't talk, asked if he could call back in an hour. He never did.
