Rude, Unprofessional service

I have never been spoken to in such an abrupt and rude manner in my entire life by your very demotivated staff member namely Lea Mokoana at the Lakeside Mall Woolworths. All that I wanted to achieve was to exchange an item that was too small, unfortunately it was a gift and therefore i did not have a slip as one does not receive gifts with slips. I cannot believe that her attitude was so appalling as I am a loyal customer at Woolworths, who spends thousands of Rands there on a monthly basis, which includes clothing, food and gifts. Just to clarify that her exact words that she used upon refusing to assist me is that "she does not feel like it" I feel that i need to make this clear that I am the customer and there are other avenues that can be used to rectify this type of behaviour as at the end of the day I do pay her salary. What happened to TCF? Am I not the customer anymore. Do i not have rights anymore? I have no problem going to the consumers board if an amicable solution is not reached in a timeous manner as I am highly upset. What happened to 'Tis the season to jolly'

Please contact me regarding the above urgently. KimandNoni ********** 215
