Just got a call from this same number and it was listed as PA. I did not answer it or call it back. It only rang about half a ring. I hope they catch whoever is doing this and keep them handcuffed for 40 years so they can't use a phone or computer.
It only ringing a half ring for myself and others leaves me suspicious that it may route to an expensive overseas line when you are tempted to call back.
Called my cell phone at 1:35pm Eastern Time on Saturday afternoon, Feb. 1, 2014. Left no message. I only just discovered the call so that is why I'm late reporting it.
