Bad treatment and refusal to offer a service

I’m totally disgusted and never buying any product of Galxboy because their service is very bad and their policy terms only benefit them even worse because they are not visible to see on their website and their receipts. They run that store like it’s a ****a shop before getting assisted they have to call the manager which clearly states that there’s no assistant if the manager is not in store. I wanted to return an item i bought online and I’m being told it’s out of the 14 days period while i had tried to log a refund online I was told i would be charged extra for that hence I waited to get chance and go in store than paying to get a service and to my surprise I cannot do a refund or better yet get a gift voucher without calling customer services. When i finally call customer service and log a complaint I’m being told that I declined a gift voucher instore and that was said by the “area manager” as she’s the one that was contacted by customer service for my complaint, while I’m the one who suggested a gift voucher. When it comes to giving good customer service, this company has a lot of learning needed because wow, it’s my first time ever receiving such a treatment it’s as if I didn’t pay for that item
