Another Unresponsive Client Support

I'm posting here because it seems the Chessnut team replies faster on Reddit than through their official contact address, despite their claim that "we commit to replying within 24 hours." (https://www.chessnutech.com/pages/contact-us)

I took advantage of the Black Friday sale to order a Chessnut Move along with the 2-year warranty extension. Unfortunately, after completing the payment, I realized that what had actually been charged was the warranty extension for the Evo, not the Move.

I immediately contacted customer service asking for either a refund or an exchange for the correct warranty extension, and I clearly stated that I was willing to pay the price difference if necessary. After 72 hours (not counting Saturday and Sunday), I sent a follow-up email. It has now been another 24 hours, still no reply.

At this point, I find it absolutely unacceptable and frankly outrageous that they appear to show so little regard for their customers, especially when their website promises the opposite. So I'm posting here in the hope that this will finally get their attention. I have also opened a PayPal dispute, since that might be the only way to get an actual response.
