eBay is a horrible platform for sellers. I have had an issue with a customer who put through outrageous claims and provided no proof, while I provided clear proof that contradicts his claims and yet they side with the customer. They expect their sellers to, simply put, become slaves to customers and say yes to whatever the customer says. They expect you to compensate and issue refunds to scammy and dishonest customers and will take their side on every occasion. It is a very bad platform for sellers as they treat sellers unfairly and not willing to listen or comprehend your point of view as a seller. If you are looking to sell products or open a business, avoid eBay and try Amazon instead. Unlike eBay, Amazon are fair to their sellers as they are to their buyers and they are slowly overtaking eBays market in Australia.
