seller used this 1 account to inflate bidding what is my recourse?

[jabl4815]

so I bid on a few things on this sellers store. I kept seeing the end price being wellll over what the item was worth. so I checked the bid history and it seems like there is this 1 account that only buys from this seller. what is my recourse, as I think I am entitled to the item at the price I bidded on before the fraudulent bidding started
this was the bid history of the winning bidder. as you can see they only bid on this seller 
I blocked out the item so they don't get harassed etc 

will ebay retract all the bids?? and let me have it for my original bid??  What usually happens ?? 
its not just a maybe. you can clearly see just the 1 account all he/she did was bid on this seller.

Now that the listings have been removed the item number will do you no good.

Spot silver is currently about $A40 per ounce, so unless it was a coin of some collector value, at $45 for 1/2 an ounce of silver the price is well OTT
