The past two days this number has called me several times.  I haven't answered it, and they never leave a message.

I've received numerous call from this number--past midnight as well. The first time they called, the first speaker (a woman)spoke in Spanish. When I said I did not speak Spanish, the speaker continued. After I repeat it, finally a male speaker came on and spoke in English. I explained that they must have called a wrong number and hung up. They have called back at least four more time, at varying times throughout the day today.

Theses people called three times after midnight, the other night, and never left a message. apparently they only communicate with you if you answer.
