Refund lack of support

I’m getting very frustrated with the lack of support from customer support. I sent my order back and it was received on April 15, 2021. No refund yet. I’ve called support and they always say they will escalate it and I’ll get a call back. All I get are crickets. Ring customer support has really gone downhill since the early days. I would love to get a way to tell them directly how bad it is but there is no way to do that. Anyone have any ideas?
