I don't answer phone calls from numbers I don't recognize. This number has called me 3 times, back to back. The first two times I missed the calls. They didn't leave a message. The third time I answered and no one said anything. I added them to my call reject list.
Received a call at 5:45 am on a Sunday. A heavily accented young woman spoke in a language I couldn't understand and hung up. I'm not sure, but I think this was not the first time she's called me.
