Note: you're not contacting eBay by posting on these boards. They are public forums on which any eBay member can post, and the responders are, like you, fellow eBay members who give voluntary helpful advice and information. (The standard of help is usually well above the type of cut-and-paste help provided by eBay customer service.)

Click onto the link. At the bottom of that page there will be an option to phone ebay. (eBay's call centre is generally speaking not available during this pandemic, but for hijacked/hacked accounts, there is still a phone option.)
Use the "Have us call you" option for preference.
