Over the months I have learned far more than I really wanted to know about filing Disputes on ebay, what I have learned I was amazed that some people did not know even people that have been  here longer than myself.
When yo open a dispute with a buyer/seller  it will stay down on the left side of your main ebay screen under        Dispute Console you may at anytime click on that    Dispute console and see how things are going.. The first step will be to file the complaint, you will see a white check mark next to the dispute afterthat meaning its pending.. then the start of the long 7 day wait comes. you may write  in that response area everyday every hour if you wish.  the person does not have to respond. thats fine, after about 8-10 days the check mark should turn blue meaning ebay has made a ruling LOL  but it usually does not. after ten day you have the option to hit the close dispute button and 3 questions will pop up. IF the other party did not answr you at all just jit could not work this out.  and hit closed. you will see a gren arrow in front of the now old dispute. meaning your fees were returned.  make sureto add in your  begining remarks to ebay that if this party does not comply and you do win you would like a strike given to them apon the ending of this mattter.. NOW heres the tricky part. EBAY will NEVER close a case for you.. IF you wait more than 30 day your out of luck so stay on this..  YOU must close this case on your own. and give reasons why. then and only then will ebay  grant you  your fee return. I hope this helps . I had to find out all this the hard way.
