I purchased a phone at the last auction that doesn't work how can I return it

As stated at the auction all electronics you have 3 days to return them. Call them but 9/6 is your last day to return.

Ron above is right electronics are returbable for 3 days if they dont work

All electronics are guaranteed for three days I believe. Call them to confirm.

I believe all sales are final as stated at the auction.

I don't believe you can I'm pretty sure they state at the beginning of the auction that all sales are final

Dont think you can
