VIP refund?

Hi all, quick question please.
I purchased around 900 days' worth of VIP a few months ago. I've been playing since launch, hoping that with each new mod the game would improve—but it never does. In fact, it keeps getting worse by the day.

Has anyone managed to get a refund?
I don't care about recovering the full amount I “invested,” but even getting 50% back would be nice.

Why?
The grind in the latest mod is borderline unbearable. Not to mention, it feels like no one is playing this game anymore.
I'm on Xbox, by the way.

I submitted a support ticket, but I haven’t received any response so far.
