Disappointed customer after experience at Edgar's Westwood mall

Good day I experienced terrible service yesterday 13 December 2019 from the Edgar's clothing store in Westwood Mall, Durban. I went into the store with my girlfriend to get a refund for a shorts we had bought at Edgar's which was not fitting my girlfriend's father. I did not want a voucher or to exchange it for something else... has I saw something else for him at another store. The shorts still had the sale tag on the shorts I had left the receipt at home. The cashier was rude to my girlfriend and I and said there is nothing they can do without the receipt even if the tag is still on... Then we asked for the manager. He was unfriendly, rude and showed no s****s in customer service training. He acted as if we stole the shorts. Told us that unfortunately he cannot do the refund because there is alot of cases of shoppers *****ing stuff n trying to resell and others making **** stuff putting **** Edgar's stickers and sale tags..... We purchased that shorts few weeks ago using my girlfriend's debit card(cash) and we swiped my Edgar's card for points. He took my girlfriends debit card and my Edgar's card and checked on his system which he said is very complicated and only if he had exact details can he do refund... He found nothing on his so called system and acted has if we had ****** the shorts because there was no proof on his system. At that moment I was very upset and told him OK I'd be back in a hour as we will drive back to Newlands and I would look for the receipt. Newlands West is a far drive from this store and I was also upset about that too because I had other things to sort out for the day and other shopping. An hour later I went back to the store with the receipt and again he, the manager was so rude n spoke in a harsh tone... To me as a customer it was a very disrespectful tone which upset me as their was other customers present there. He was acting as if he was doing me a huge favor by doing the refund for me. I have rights and I am fully aware and had training done few years ago about the Customer Protection Act. I've never had this problem before at any other Edgar's store we I wanted a refund or wanted an exchange without a receipt but with the tag on still.... I usually do my shopping all the time at Edgar's Westwood Durban every month and I will never forget my horrible experience at Westwood mall edgars. I will no longer go to that Edgar's store in Westwood and I will tell my friends and family about this experience especially during the festive season....I would like a phone call from your head of department management team to contact me about this matter as I am totally disgusting by the way we was treated...... The cashiers name was Sthembile Knosi and the store manager's name was Ashveer Rajcoomar.

Kind regards
