Can’t refund my buyer

My buyer cancelled an order and she can't get a refund we have tried everything Ebay has said that it's because of a glitch in the system meanwhile my buyer has waited nine days and still no refund as a seller this is appalling. A glitch in the system that for over 10 days has not been fixed meaning if buyers cancel their order they don't get a refund 10 days later I still don't have the money in my account either so what is going on eBay! has anybody else had this issue
