I was involved in an auction to purchase a house and was the winning and only bidder. I felt the auction had been unfair and refused to sign the contract. The real estate agents for the vendor threatened breach of contract but my view was that there was no signed contract. The agent said the auctioneer could sign on my behalf against my wishes. Can I simply walk away from this situation. I based my claim of unfairness because the vendor's agent was bidding on my behalf on the understanding I had given him authority to do so which was incorrect. Where do I go from here? I didn't want to buy the house in any case.
