Answered "Hello" 3 times no response back. WTF?

they called but i couldn't get to the phone. i called back really late after seeing this site but it went to their voicemail which doesn't say who it is and it said the voicemailbox is full.

calls every night & does not answer when I pick up the phone

Collect call from Harris County Jail. Area code 713 is Houston, TX. I hung up before they could charge $5.00/minute. I don't know anybody in jail, especially in Houston.

Many people get calls from this number, sometimes twice or three times a day. Upon answering, you may either get a telemarketing pitch or no answer at all. The things they have tried to sell, based on comments from those who have received calls from this number, include free magazines from Best Buy and debt relief. The company has been called "Portfolio Recovery Services", but that is likely not the only name they go by. They are based in Norfolk, VA. Some people who have asked them to stop calling only get calls from a different phone number. These calls occur in some cases up to two or three times a day.

Never stops, every day.

Calls me and hangs up after 2 seconds after I answer the phone. Doubt it's a prank call.

Called twice today, hung up both times when i answered. No response from the caller after several times asking for a reply.

I did not answer the phone, but it said they left a voice mail. There was nothing on the voice mail, but the VM prompt said, "this message will be deleted from your phone".

Phone rang I answered it hung up.

Multiple calls to my home and cell daily. When I called Cricket I was told I'd be taken off their list. NOT TRUE.

i have received more than 10 calls to mexico city
