Why are you trying to call eBay CS?
eBay CS is short-staffed at the moment due to the Covid-19 situation.
If you try the eBay “Help and Contact” link at the top of the “Home” page then “Call-back” and “Live chat” may still be available, but you may have to search for them.
Do you really need to contact eBay CS?
If you are a buyer most problems can be solved by completing a case in the Resolution Centre: https://resolutioncentre.ebay.co.uk/
If you put your issue here someone will probably give you a better answer sooner than eBay.
