I had this number call today at 4:25 p.m., I answered with no reply from the caller, though I did notice I heard what sounded like keyboard clicks in the background - as when talking to someone who is using a computer keyboard at the same time. I called back with in 15 minutes, no one picked up and no answering service did either. It is possible it is a collector. As a note, I personally have been sending resumes off to Tech position posts on Craigslist and have noticed some complaints from others doing the same that have encountered "illigitamate" posts and possible data mining by these posters for neferious reasons. I did a Re-verse Lookup on the number over the web via Intelius.com, its there as a wireless number, but you must pay 14 dollars for the record for that number.
I started getting calls from this number today. They were at 8:48am and 11:48am so far. I also don't answer if I don't know the number. If they were calling on my home phone I could block it, but they are calling my cell number.
I received two calls today, the first call I missed so I tried calling it back and it just says "the service you are attempting to use has been restricted or unavailable". I answered the second call and she asked for me then I told her she had the wrong number and she just kept saying that she put this number down as her phone number and I just kept telling her that she had the wrong number.
