Multiple calls a day. No messages left. On do not call list and even have a no solicitation message that they have to get through to make the phone ring.
Woman with a heavy Eastern European/Russian accent stated she was calling because I've won a trip of a lifetime because I have one of the following Visa/MasterCard/Discover/American Express credit or debit card. She then wanted me to confirm I had one of those. She said she was calling from Helena, Montana but area code 720 is a CO exchange. When I told her my phone number was on the Do Not Call list she had no clue what that was. Seemed like a total scam!
This phone number is used by a European calling card company. I have a friend in Germany who uses a calling card to call me in the states and this is the number which shows up on the caller i.d. The call apparently is routed from Europe to a local switching station which uses this number to process the calls.
