This is a collection company. They are very rude. Received a call and didn't answer it and they didn't leave a message so I called it back and the guy that was on the other line already had my number and was asking for it. I would give it to him and told him I wanted to know why they were calling. He wouldn't give me any info and said that I needed to idenify myself. When I told him I wouldn't he got very defensive and rude.

612-326-3345 is a collection agency by the name of BCR.
BCR is extremely agressive, will auto dial you many times during the day up until 9 PM. If you want to stop collection calls, according to the Fair Dept Collection Act, you must inform them to stop calling you. If they do not stop calling you, then you may file a complaint with the FTC and FTC will take enforcement action against them. You may also be awarded monetary damages against the collection agency as a result of their violation of the Fair Debt Collection Act.  ... very serious stuff if a collection agency does not follow the law.   ... Good Luck.

I googled this and sounds like a scam to me...

I tried to call and very nicely asked them to take me off of their calling list. I told them I am a nice person and it is not right that they are aggressive with me and rude. I told them I didn't want to, but that I would file a complaint. The response I got when I said "Please take me off of your calling list..." was "Why?" Very snotty. Then the man was really out of breath and said "yep...k...." and that was it. Didn't bother to ask my name or take down any info. I didn't have to give my number or anything. Pretty sure he just completely blew me off!!!!!!!
