Exchange policy

It was the worst Edgars store i have been to. I had been to the store on Sunday 3/12/17 and i purchased branded items which were 30 % discounted when i got home and tried one of the Ecko tops on it was to big and i went into the s**** on Tuesday to exchange it for another Ecko top which was the correct size . When i got to Customer service KAYURI MOBARI credit Manager told me she could NOT exchange it because it was a different style. But yet the same price and same brand and i had my till slip. So what the hell was the problem. The credit Manager was very rude and she has no customer service at all. How does EDCON employ people. Im a loyal edgars customer and i am very disappointed with the service and the policy structures in place. I paid cash and i can take my money to any store instead EDCON has lost a customer. And i think rules for exchanging or crediting need to be explained to the staff with immediate effect.
