Have they actually not paid full stop?
Or have you not signed up to Managed Payments so won't get your funds at all
Or have they paid and your money is on hold due to you being a new seller in eBay's eyes and your funds will be on hold for 30 days?
If they have not paid at all and it has been 8 days, then yes, you should have the option to select 'buyer did'nt pay'
