Do you know that you don't need to chase EVRI on behalf of your Seller? Just open an Item Not Received case, and watch the date to escalate it to eBay if the Seller doesn't act.
Since you are a Private Seller sending with Simple Delivery, even when your Item is stuck with EVRI you don't need to chase them anymore. Just have your Buyer open an INR and leave eBay to do all the work (usually they refund your Buyer and let you keep the money too.) That is if you haven't opted out of using EVRI for SD entirely!
