Who called from 2705947264

Had a ring-a-ding from another ding-a-ling, on my cell phone, a number I've only had since last September, and do not give out to just anyone, so they obviously don't know who it REALLY is they are annoying.

Called and hung up before I could answer. Then sent a text asking if they can call later.

Didn't answer

Received a call just now, did not answer and caller left no message. Am going to block this number

Called-phone was in the other room; it stopped before I got to it, and left no message.  Caller unknown to me.
