I received 3 calls from 207-579-5485 all in about 15 minutes, I did not answer the calls, and they did not leave a message. My reverse phone lookup on my iphone cannot identify the caller.
I've just received 2 messages in a 1 hour span from these people too, and the first one was at 3am and the second call was at 4am. Woke me up out of a deep sleep! When I try to return the call, there is a recorded message where the operator says, "We're sorry. The number you have dialed is not correct. Please check the number and try again."
