It is unlikely that the people you are dealing with have done anything wrong in trying to raise your bids. When bidding on a project, it is common for people to try and get the best deal for themselves, and this may involve raising bids in order to secure the job. It is important to remember that, unless you have agreed to a set price, the bids are only an indication of what you are willing to pay, and the other party is free to counter with a higher bid if they wish. As such, it is unlikely that the people you are dealing with have done anything wrong in trying to raise your bids.
