Online Buddies review: Online Buddies-Unknown Charges

So i checked my online banking info and mysteriously there's 4 charges by 7273 OLB ONLINE BUDDIES; 2 for 0.00 bucks and 2 for 7.00 bucks. I've got an account on Manhunt and know that Online Buddies is the name they say in the description but i have NO CLUE where these charges are coming from. I contacted them before about this but couldn't resolve it since i didn't have the card # used for the purchases...

Please, if anyone can help me, tell me how to correct this. :
