Bad customers service

It's very bad to notice that jet is giving their management the right to insult us customers and give us bad customer service.on the 4th May I went to jet jabulani to return a jacket as it was losing colour after I washed it.i went there just for exchange nothing else.but to my shock I meet a sales lady who referred me to a store manager by the name of Phillis who never helped me but insulted me.i was so shocked because I did ask her if she was referring to me when she said '**** this kase ladies think they r better nxa.another collegue of hers asked which then she pointed to me.....it was very bad as other customer were watching at me as if I was a fool.nd jet jabulani staff.my question is.....is it how jet jabulani management is to treat us as customers?.is it ok that customers are insulted and humiliated in that store?is it ok that jet headoffice does nothing to such cases?I'm ashamed of the service jet jabulani is giving to customers
