Very POOR MANAGEMENT

Good day, I was at the Truwards store over the weekend, I paid my account and wanted to buy a body mist, well let, me tell you about my experience, I recived an R100 voucher to use and the sales lady exsplained to me why dont I take a nice gift pack insted of the body mist I will recive an R100 off, I then desided that I will indeed do that, whilst we were bussy talking some lady that works for Truwards screamed from the back of the shop that she can not use the voucher against a gift pack, the lady that assisted me was embarrased and told me that she was not aware, when the screaming lady came to the till I asked her why can I not use the voucher to purches a gift pack and she shaid its just how it is, when you buy a giift pack you only pay for one bottle of perfume and the second one you get free, I then exsplained to her but its not saying anything on the terms and conditions I then told her that I will contact head office to understand better, she the sarcastically said you more than welcome to contact head office. First, you walk all innocent into the store to pay your account and to purchase a body mist, then all of a sudden the lady interfered and screamed at me and the sales lady from the back very unprofessional!!!!!!!!! Then we get told what is what in front of other customers and I got so embarrassed and I could see that the poor sales lady was embarrassed as well, I presumed it was the manageress , I just want to say that the way she handled the situation was on cold for and very disturbing and unprofessional, people like her take authority for granted and let customers feel worthless and very discussed!! I would like to know who de He.. she is to scream at me and to embarrass me in front of other customers and who gives her the right to talk to her colleague like that!!!!! I phone this morning only for the person, on the other hand, to put the phone down in my ear. So I guess that this is how the customers get treated If you don't want to give me a voucher don't!!!! Don't waste my time and scream and shout at me and embarrass me in front of others you don't know me at all!! Your management s****s suck and the way you treat people is un-cold for! people like you should not be employed let alone work with other people!!! Very poor management !!!!!
