Is ebay aware of scammers pretending to be ebay?

I have received a call from this number todayAdvising that a 299 dollar purchase was to be made on my account.  SO I went to option 3 to speak with someone who got **bleep**ty with me and they were

asking me to set up something in my computer for security  but DONT log into my ebay account.

I closed off the call as they called on a number that I dont have registered with ebay.
