The item not as described claim process sends your request to seller first then you ask ebay to step in if the seller doesn't respond and resolve it says. So status is waiting for seller to respond now. So just doing normal process I believe
I normally use the "Ask the seller a question about the item" to get them to resolve it peacefully without dinging their ebay score. It is almost always an honest mistake, for example where someone used a stock photo of a Dell SSD and shipped an HP one (which, of course, Dell's utility won't update the firmware of).
I think there's only been one time since I've been on ebay (which dates back to Pierre and Meg) where I had to go through the actual dispute process. Eventually ebay/Paypal (they were still one company then) sent me a prepaid label to return the item to the seller. The seller refused delivery of it, so ebay/Paypal refunded my money.
I have had sellers get snotty with me and I've had to threaten to go through dispute resolution. One memorable time was for an instrument cluster for a BMW. It had had LEDs unsoldered and other damage. The seller said he got it from his cousin when his cousin changed it on his car and he wasn't responsible for that, tough luck etc. After a few more back and forth messages where the seller refused a return / refund, I looked at his other listings and found over a dozen more instrument clusters and asked him "how often does your cousin change his instrument cluster?"
