Pathetic service received

I was at Foschini Clearwater to exchange a jacket as the jacket did not fit, the jacket was bought at westgate mall I ddnt know that the jacket still had a tag, when I came inside the store the sensors beeped,the was no security or any store representative at the door so I went ahead, when I was leaving the store it yet again beeped at the door, then a lady shouted saying im calling you,when I approached her I asked why she shouting, with attitude she rep**** its in her nature,i explained to her what happened,before I could complete my sentence,she requested a slip,when I told her that I ddnt have it and the consultant at the counter had already assisted me on where I could get my size,she started shouting,accusing me of theft,pointing fingers called her colleague,when I asked her is this how she treats all customers and when i.told her I am going to report her behaviour,she told me to go ahead telling me her name Jane Nakedi, she lives at diepkloof,her store manager is Cindy Christain,she then added that I should even post it on facebook and Twitter,never had I felt so embarrassed and disrespected,if this is how you train your staff members,i suggest you close your doors!!!
