JDsports refund.

Hey!
I'll get my salary soon, so I'm thinking about refunding some clothes or something. JDsports offer really nice stuff, and I'm willing to do them. I just read that people have refunded them, but one guy refunded with paypal, and they didn't respond, he says he got full refund apparently, one other guy said he got to fill out an email for the refund, but got only partial refund.
How should I go around this, refund through paypal or try to get the refund through support?
Please don't waste anyones time with shitposts!
Thanks!
