Responding to a Angry Buyer

Question for you experienced sellers out there, is it even worth your time, or my time in this case, to try and message with a buyer that recently bought an item and has come in with messages, accusing me of false descriptions and trying to screw him over?

At this point, I have not even tried to send a message because it’s pretty clear that nothing I say is going to satisfy this individual even though I am confident in my description and his complaints about the lot are spot on with my description. He recently ended the message barrage by saying he will contact eBay for resolution.

Respond or don’t bother??
