You say you rarely leave negative feedback. Out of 73 feedback left for others, 28 are negative. That is far from "rarely". I'm guessing your seller saw you as being a liability and baled out. I can only assume that the feedback you left was another red dot. As you have seen, sellers are able to get red dots removed.
As for the seller not caring, sellers often hear about illness or going to hospital when someone hasn't paid. It's the oldest excuse in the book. Not saying that is the case with you, but if I had $1 for every time someone said they got sick or went to hospital, I'd be a very rich person.
"I wonder how the people who left unpleasant messages on here would feel if this happend to them while worrying their partner is going to die."
You're not the only person who has someone they love try to die on them at the most inconvenient time. In fact, there are a few here who have had that happen. Myself included. I ceased all eBay activity when that happened. I paid for any outstanding purchases and ended all my listings. I was then free to travel the 4+ hours each way to see surgeons, oncologists, speech pathologists, have MRI's, CT's, PET scans. 3 years later, we still have to make those trips several times a year.
You aren't the first person to receive bad news and you certainly won't be the last. Most sellers don't really care because they have heard it all before.
I hope your partner is OK and can have the wretched thing fixed.
