Postage and tort law

Hi Folks 

 

I do hope i word this correctly here goes 

 

 

 

drum roll  ....

 

 

Ok   say for arguement sake 

 

I posted an item 

 

the buyer did not recieve the said item 

 

Can Ebay be accountable ,,,, to help look  or find the said item ???

 

as Ebay has taken  a  % in the postage costs

 

 

which to my knowledge would come down to a tort case???
