ebay takes on accountability for items that don't arrive

eBay takes no accountability for packages that are not delivered after 30 days. I bought 2 items in May 2019 and it is now December. 2019. I since June I have tried to contact the sellers of these items on the eBay website and app repeatedly but only get an error message. When I contacted eBay customer service I was told no refunds after 30 days even though it take more than that to get to South Africa and that they can't contact the seller on my behalf to find out what happened. I repeatedly sent them screne shots of there website malfunctions to no effect. Other than the eBay website which refuses to let me contacting the sellers to get my money back or my items there's nothing I can do under the eBay policy. This is a **** and ebay's customer service was appalling, their attempts to weasel out of taking accountability for there failures means I am never getting my money, items or using this terrible online service again. Thanks for nothing eBay
