It sounds that communication was just terrible between you two.
What a terrible buying experience!
Let's go over some things you mentioned.
The biggest issue here is that your agent didn't explain his suggestions to you correctly.
An example: suggesting consulting contractors - who often are
extremely helpful in evaluating the costs and possible other potential issues with the property -
it is a very good suggestion. If there are problems, you do want to find them out during the inspection period, and get out of the deal, if necessary. Inspectors have certain limitations as to what they can do/say, and they are often wrong on the costs or repairs (they are not contractors).
Emails are also better for the both of you - it's a record that can not be disputed.
It's protecting your interests, and it is protecting your agent's side of story.
Sometimes, people do inspections and make their offer afterwards, especially in a short sale or foreclosure transaction. If this was a normal sale - then yes, inspection should have been done after the last initial was put in on your contract/purchase and sales agreement (depending on the state you are in).
The main person who could help you immediately, is your agent's broker.
If he/she does not respond, send them a registered mail letter explaining this situation and requesting an immediate meeting. If there is no responce after the letter, it is time to call your state's real estate commission's office and ask for their help/guidance. You can also hire an attorney.
I'm very sorry that your buying experience was such a mess!
I do hope that from this point on things will be better for you!
Hope this helps,
