Instagram has become the go-to public forum for celebs to air out grievances against each other -- just ask Soulja Boy. Luxury car dealer Precision Concierge New York got into the game Sunday when they posted screenshots of separate text conversations they've had with Soulja Boy and Sean Kinsgton.

Apparently, the two recording artists have failed to pay back bills they owe the Manhattan-based dealership. They accuse Draco, who's always flashing racks and racks, of owing $650 to their L.A. branch since last October. It's a paltry considering his fortune. 

They also go hard after Sean Kingston accusing him of owing $4,200 since November after renting a Cadillac Escalade for a whole month and a Mercedes-Benz S-Class for a few days. They say they've chased after the shifty crooner when he gave them a check that didn't work. They even put up a pic of the bad check. The two supposed deadbeats have yet to respond to PCNY's accusations.
