Yes eBay know

As do 99% of other members here, so posting under community feedback won't be seen by anyone who 'does'nt know'

People who have never used eBay get the same calls

But why oh why did you play along?. You would know you did not make any such purchase 

You could have kept yourself safe, hung up and contacted your bank instead

Now these scammers will tell their scammer mates that you are someone who will go along with whatever they tell you

At least you did'nt do the computer bit, but you have still done more than enough to put yourself at risk
