@ard1947,

If you wrote "may be many bugs", you'd be correct (in my view). Unfortunately, there's no way to contact eBay's IT to tell them, "This bit of code is wrong" or "This is deprecated" or "This won't render in [insert web browser]" or "This is glitch-ridden".

Contacting CS will result in the usual placebo remarks designed to get you off the phone as quickly as possible while uttering soothing phrases from scripts.
