Disgusting service - Promenade branch - Mitchells Plain - WC - Lost customer

Today, I went to Soundtech, Promenade mall, Mitchells Plain, browsed and only wanted headphones, but ended up buying a remote control and a android remote, going over budget, but because its Sountech, I though why not. bought my goods and the at the till, I showed her my app I was using for this android box, and she saw the name and I bought it thinking its maybe Universal, I assumed, my bad. (no testing was done on 3x electronics purchased, nothing explained on any warranties, no customer interaction). Arrived at home, tested the equipment and then the remote does not work (remote comes in plastic sleave - no instructions, no box). then took another taxi back to the branch and explained and I was then at fault for not asking more questions on the remote, which I will accept, by this time the lady at the till and I assume a manager, making me aware of the above, I then asked a refund and was informed it would need to be an EFT ( 2-3 days , and as I remove the plastic sleeve the remote was in, that was considered a breakage fee and without this sleeve 🤣, the remote could not be sold again (by this time he also realized the remote didn't work as I watched how they fetched another one after replacing batteries on the returned remote - which I supp****, I knew then that the remote was faulty I had brought back, but the manager did not say that, he just wanted to charge a breakage fees as I had a return and he was angry as he was trying to intimidate me as he was taller and bigger than me, acting like a vulture, showing me look at the receipt (was never explained to me, at purchase) of a refund policy - I eventually left without my refund of R300 and batteries I bought for the remote. . POOR CUSTOMER SERVICE - I would have probably accepted your return policy, should your staff there just have had basic manners and some sort of customer etiquette, its 2024, customer service is the name of the game, anyways, they lost a customer and probably more to come.
