saw soething on ebay that i wanted
read the description
bought somethng last friday with a buy it now
reread the description and though "oh shit, that's not what i wanted"
contacted seller through ebay to explain and said "look, my mistake, i'll pay the relisting fees etc as it's not what i wanted" etc etc
waited
setn aother one on saturday
waited
sent a email via the contact page when he sent me an email requesting payment
yesterday. nothing
today, nothing
what can i do?

other than wait for him to reply to either message or the email that it stats he wishes to be contacted via?
can't afford to waste money on something i don't want, but at the same time, don't want to leave the guy out of pocket either

or do i wait the 90 days?
