Had a charge on my credit card showing this number.
Do not remember anything about it.  
Been trying to call it to see what it was and who did it and can not get anyone to answer.  
Everytime I call, a recording says to call back later.

i have the same problem as you billy mac...
my credit card company cancel my card & refunded the amount.
Not sure who they are.

I also had a charge from this company I did not authorize. Have any of you recently purchased anything from Amazon with the same card? I believe this is how they may be getting the card information?

Yes, I had made a purchase from Amazon.com with a card that I rarely use and a couple months later a charge for $8.85 showed up on my statement from rhinoresourcesllc.com.  I am currently disputing the charge with my credit card company.

I didn't get a call from this number that I'm aware of but I have been battling a credit card charge for almost two months. When I first reported the charge to my credit card company they credited the charge but about a month later they reinstated the charge and said the company - rhinoresourcesllc.com said the charge was valid. I have resubmitted a complaint again with my credit card company but so far haven't heard anything back from them. I must have been on the front end of this scam because I am just now seeing others report this.
