Yoco Card Machines

I hope you’re doing well. I’m reaching out for assistance with an issue I’m having with Yoco’s customer support. I purchased two Yoco card machines at a garage sale, paid in cash, so I don’t have a formal proof of purchase. Now, I’m struggling to get the ownership changed, as Yoco requires a proof of payment or ownership. Despite trying to work with them through their chat platform, I’ve stalled. Could you help me escalate this issue? Your past support has been amazing, and I’d really appreciate your guidance. Thank you so much in advance!
