I received a payday loan from mycashnow.com . i have some issues with them but then a few days later I received 200 dollars and another 200 dollars from cmg group llc and djr group llc. I haven't signed anything or didn't even know they were sending any money till I received an email and I sent and email back telling them I didn't request any money from them. I don't know what to do. I tried calling but I just get voicemail and my credit union isn't being very helpful.....Please help!!!
