Family Dollar

I purchased a 18in grill on 06/07/19. The grill was defective and missing some parts. I went into the store on 06/10/19 to return and the employee named sharice was there when I purchased the grills. She then stated I couldn't return it. She said that I had to wait for the store manager. I have my receipt. She was nasty and said well come back at 1.
