These people just called me and claimed that Expedia or Orbitz gave them my number from their "own internal system" and they wanted to get my info for some trip I'd won. The person I spoke with was a lady who speaks English decently but has a noticeable accent and trouble understanding idiomatic language. I called back and got a machine poorly trying to imitate a switching error: "The call cannot be completed as dialed."
My phone was on silent and I had a missed call from this number. Less than 5 minutes later my husband also gets a call from the exact same number. He answers hello they say hellooo & he says can I help you, they hang up.
