If you have a non payer you open a non payment dispute at the bottom of the page under Resolution Centre
You can open one after 2 days and close after another 4 days
You get your final value fees back the non payer gets a strike and neither of you can leave feedback
If you dont do this then ebay do not know you did not get paid and you have to pay the fees
You have 32 days to open a dispute
If it was the wii then you are a bit previous about payment as it only sold today
The buyer could be at work or not at their computer
If it is the phone then you are out of time for a dispute as you have 32 days
