I get atleast 5 calls from this number every day. They start calling at 9:00am and they don't stop until 9:00pm! They claim to be a collection agency handling my student loans but when speaking to an agency that I used to deal with they told me they were the only ones handling my loan repayment.. very sketchy.

I get just 513 on the caller ID and when I answer it is a fax.

I got a call from this number and they claim to be an executive head-hunter company.  I don't know what this is about, but it sounds a little sketchy to me...

Got a call from this number 513-000-7533. NO message. Caller ID states "Name not found". Another scam.

I have been getting this number showing up on my home phone for about a month now. My home phone is unlisted and only those who need it have it. We are basically debt free, so I know it wouldn't be a collection call..I finally answered it out of curiosity today. The woman began rambling so fast that I could hardly understand what she was saying but she claimed that she was calling about my home that was listed for rent several months ago. Here's the kicker: This phone number was not associated with that ad AND the ad was listed on a private website that wasn't available to the general public. She rambled off the address of the rental and said that she her company "Runtime International" looks for corporate and government rental homes (whatever that is) and she asked me if I "would know what the monthly rental amount would be". I told her that the home was no longer available and she got rude and said "so, do you know how much the house is being rented out for, how much do you get for that house?" I laughed and told her that I do in fact know how much we rent the house for but I wasn't interested in sharing that info- I was about to interrogate her on where she got the info but then she hung up on me.  

I assume that the "513" is some kind of spoof number, but can't imagine what the heck this call would be about. It really bothers me because I couldn't find any info on the company, I know it's some sort of scam, but this number was not associated with that rental at all. Maybe they're looking for demographic info to feed to some marketing org? I just thought I'd share this info in case anyone else knows what this is all about. I guess it's not always a collector, we don't live anywhere near OH either.
