Body shaming , defamation of character

I went to go purchase a pair of jeans at Mr Price , Campus Square The jean was grey black , size 36 RT jeans . When it was time for me to go and pay there was no one at the till I went and looked for an employee that can help me .. she came and apologized I took that . She took the pair of jeans and checked the size of the jeans , she then said to me .. “it won’t fit you” I asked what does she mean ? She tried justifying her statement with words like “our stock is not the same , sometimes they bring big cuts and sometimes they bring small cuts” I was really discouraged on buying that pair of jeans . She was rude and was body shaming me ..
