Rainbow Shops review: discrimination from manager

I was discriminated against by manager Tiana. She had no name tag so I do not know if that is her real name. She alluded to me being a thief and refused to help me. My daughter had received birthday gifts and a shirt from Rainbow was one. I did not have a receipt since it was a wrapped gift..Tiana refused to help me exchange the shirt for a bigger size. I asked if I could find the same shirt so she could see how much it was and she said no because for all she knows it was stolen. I asked if she could look up the product number and she said no...there no such thing. I went to three other stores to exchange other clothes that were too small and everyone looked at the tag for product number and happily assisted me. I went to a different Rainbow and they simply said to get the same shirt so they could see price and allowed me to exchange the shirt without any name calling or disrespect. This woman should be FIRED IMMEDIATELY!
