on line auction bidding cock up
i spotted a pair of yamaha ns-1000m speakers listed in auction and bid £400 on them via the saleroom.com.
i was watching the auction live on my mobile and when the bidding passed my £400 i thought id have 1 more bid,trouble is it keep saying 'your the highest bidder'! the auction ended i won them for £500,the total including buyers comission comes to £608 
my worry is i didnt bid £500! im going to contact the saleroom.com tomorrow and explain,have i got any chance?
