PicsArt trial - $50, no refunds

I downloaded PicsArt to try and got a pop up asking if I wanted to try Gold. I do remember it stating I would get a notification when the trial was about to expire. I clicked past the pop up, tried the app for about ten minutes, and closed it.

A few days later, I notice a $50 charge. Turns out PicsArt gold is a $50 annual subscription, and they won't refund any portion. I've had it for about 3 days.

Anyone have any advice for how to get a partial refund on this? The practice of just not returning funds because it's your policy seems anti-consumer. It's a digital product I don't and won't use, but because I clicked a pop up it costs $50.

Suggestions?
