Edcon Bothering me while shopping

On the 09th of September, I went shopping at Edgars, Menlyn Park. While I was walking around two men with black trousers and white collar shirts with yellow Edcon sticker approached me and asked if I have an Edgars account, I rep**** yes. They told me that they will have to check on my account to see if i qualify for the 75% discount. I told them I do because it states on the tags, they kept on insisting that we check because not all card members qualify. So I went with them to the counter, they swiped my card.The guy said so he sees that I am part of the club, I said yes, I asked whats this about, he then started to talk about funeral policy and hospital plans. I requested my card back, and he refused, I asked again in a furious voice so then he gave the card to me. I wasn't finished shopping and still wanted to look around but they made me so mad that I just bought the items in the trolley. This is harassment from Edgars, if they cant sell the stuff over the phone the haunt you in the shopping store. I phoned Edgars *** to report this harassment, I spoke to Rene and she took my number and said Bernard will phone me back. I havent heard anything till today
