There's no other way to ask for a Refund aside going through Support, which you got yourself banned from and that won't be lifted.
Even more so if you want to ask for
even more refunds, when you were already abusing that, having asked for over one hundred individual item to be refunded. That probably had a lot more to do with your ban than just your reaction to the gifts you received.
If you need to contact Support for assistance
unrelated to refunds, you might still reach them with
[email protected]. But read that line a few times, especially the highlighted part. You won't be getting any more refunds. Trying to use that email to ask for one will just end up with you blocked and ignored.
