Very poor service for black customers they only consider white people as customers

I went to Mr price home this morning I waited for more than 15 minutes for the guy who works at furniture department yo help, as I was advised by Sara's that I must wait for the guy who works at furniture department, The guy came and he went and help the white lady who come after us and we told them that this white lady come after us, but the guy ignored us and other workers aswel. I don't know whether it's your store policy that white customers must be helped first or what. I am really disappointed and I will never buy from Mr Price home South Coast Mall ever again your staff's behavior was very bias and unprofessional.
