eBay review: eBay seller mashe197 and eBay customer support

I had the worst experience buying something on eBay in my 22-year membership with them. I have 824 transactions with perfect feedback for my entire time with them, but I have noticed that they are not allowing buyers in some cases to share their negative experiences. I had a seller take 10 days to bring what I purchased to the USPS for shipment and then he sent the wrong item and would not cooperate with me to get a refund. I left negative feedback and eBay deleted it. The seller's account name was mashe197. I think that eBay has a conflict of interest as they make money on sales and don't want to hinder sellers by allowing them to get negative feedback. I am closing out my 22 years buying and selling with eBay and will not return. Their customer service people either cannot be understood, give bad and incorrect advice or when you can understand them are very curt and bureaucratic.
