eBay

I have received approval to process a return but when I try to pull up the return label I get a message stating there are technical difficulties. This has been happening for four days. I try to pull up my order and it has disappeared.Any suggestions ...

For two days I receive the following message from eBay when trying to get the return authorization for an approved return. "We couldn't process your request because of a technical issue. Please try again." How do I contact eBay to take of the issue?
