This number has been calling me for days, but I kept missing the call. Finally I was able to answer and the person on the other line just hung up. I would just block this number if you can.
I agree with Ani - this number calls at least 2 times a day to my cell. I finally answered and I could hear some noise, but no one said anything. If I look this number up, it's registered to Bandwidth.com. No idea. I am putting this number on my BlackList.
