Received several calls on my cell phone the past few days

I called the number back but with *67 in front of it and I got a pre-recorded message saying that this is WCA subscriber services. We do not take calls from blocked or private numbers. Pretty sure it's a scammer. Google it.

no message, hung up when answering machine came on.

I answered, got a recorded message telling me I had won 2500 travel dollars towards a trip to an all inclusive resort for up to four people in cancun Mexico. It then put me on hold to talk to a representative, and then hung up. Wouldnt let me call back
