Got a call, hung up, when I said helloo...caller id says wireless caller.

Left no message.

Called multiple times and did not leave message.  But background noise on voice-mail suggested it was from calling center.  Called yesterday and today.

today was the third call in 7 days. Caller said "hello  hello" on my recorder. I could hear a call center in the backround. SCAMER ALERT

This number is apparently associated with 713-955-5682.  I have had the second number blocked for some time, but they keep calling.  Today, IMMEDIATELY after that number called and was blocked, a call came from the second number.  These scumbags think they have the RIGHT to call....most normal people would get the message when their number was blocked!
