Akon’s Georgia mansion is becoming a big problem for him, as yet another contractor is claiming he didn't get paid for working on the superstar producer and singer's floors.   


A company called Capital Floors has filed a $15,000 lien against the troublesome home, which is small compared to the $36,765 filed by a different company back in January. 

This contractor claims they did get paid a little along the way and the $15k represents the unpaid balance -- but says a lawsuit for another $50k in damages could be in the offing. 
Akon's reps haven't gotten back to us.
