Worse online shopping platform

On 24 December 2022 I made a purchase online then on the same day found a better product elsewhere, I was especially not convinced after seeing all the bad reviews about the snatcher product. I immediately requested a refund and bough the same item elsewhere. My request was only responded to on the 28th. I figured it's holidays no problem. Then I was told 15% will be taken off as a charge for me requests refund, I wasn't happy with that but I said okay can I get the rest of my refund. The refund was supposed to take 7 days it's been 10 days and haven't received anything. When you send an email they respond to it after 2 or 3 days. This is definitely the worst place to shop at online I wouldn't recommend it to anyone especially because you will have no assistance when you need help.
