Ebay helps rip off scammers again

Been on Ebay with a few accounts for about 25 years and things get worse every year.
I just got ripped off for almost $1500 this time and lost my item and as usual Ebay sides with a dishonest buyer and offers no protection for sellers.
Absolutely no help at all and they couldn't care less.
This ridiculous 30 day return policy is being taken advantage off.
So from what I can see you can keep an item for 30 days and get your money back no matter they do to it.
I went above and beyond to help the buyer repair the item and offered money settlement even though they admitted to breaking it trying avoid me paying almost 300 in return shipping for an oversized item.
The buyer was the most unreasonable person I've ever dealt with and they knew I wouldn't want to pay for a broken product back that could be easily fixed for $20.
With Ebay's insane deadlines dealing with it when I was away for Thanksgiving and the person in Texas time ran out they gave him his money back including shipping and put our account in major overdraft beyond the banks limits which seems insane that they can do that.
More to the story but I can't believe they just let people get away with this type of fraud and they couldn't care about all the evidence I had that he was dishonest.
They send BS messages that you cant reply to and won't answer questions or offer me the apparent seller return shipping help.
I'm just disgusted with the way they handle these issues and have heard similar horror stories from other sellers that have left the site.

Tried to edit this post to add more info but can't seem to do that.
Anyway the buyer after he gets his full refund says well I think I'll keep the item now and agrees it can be easily fixed like I said then offers me over 400 less to keep it so to cut my losses and at least get some money back I agree then never pays me and won't respond anymore and basically steals the item and ebay won't even respond and just keeps saying case is closed even after an appeal.
Absolutely appalling that this can happen.
