scammers

Caller claims to represent National Debit Card Network but cannot tell me where their head office is located or give me the number of their head office.  Scam artist.

Called a few times and after I say hello a few times it hangs up. Morons.

Called several times.  Answered 3rd time and after a short delay a lady with what sounded like an accent from the southern U.S. came on asking "to please speak with the owner".   Scam.
