Ok , let me tell yours a story , My friend "A" sell computer parts to "B" , indicate the items is NEW condition & attached with invoice & T&C also .

So they "COD" the items at JB . After 9 days , "B" inform "A" got 5 items got problem , need exchange . Thus "A" agreed and inform "A" supplier for this issue. But next day , "B" call "A" said all items sell to him need return due to selling him second hand & pulled items. And now keep chasing "A" to fully refund money to him .

After "A" view the picture from "B" together with supplier , confirm that the items is not belong to seller . 

This buyer trying to cheat "A" and exchange used part and ask "A" to refund all ...... very serious case for this .

So what is yours opinion abt this case and what is actual means "COD" ???
