I received several calls in a row from this number, when I finally answered, a woman with a thick accent told me I had a package in DC. I said they had the wrong number, the woman was very persistent, hung up, called back, put a man on the phone... It was very strange, I think they were trying to pull some sort of scam. I said not to call back and hung up, they called back twice and I ignored it, but ever since then I've been getting a lot of calls from "unknown numbers" that I just ignore... Very strange experience...
