"Love and Hip Hop: Atlanta" star Lil Scrappy says his daughter was left in tears Sunday afternoon ... after a salon owner refused to serve his family because they're black.
Scrappy tells TMZ ... he put a down payment on a little girls salon outside Atlanta for his daughter's birthday party -- but when he and baby mama Erica Dixon arrived 20 minutes late to their 2 1/2 hour appointment, the place wouldn't let them in.
When Scrappy complained, citing the down payment they already paid ... he says the people running the place -- who are white -- allegedly told him they didn't want to serve "you people."
Cops were called -- because Scrappy didn't want to leave without a refund on his down payment -- but officers got him half the money ... and the salon agreed to mail the rest, so he left.
Calls to the salon went unanswered.
