Why not take the high ground on this and simply c all the broker back. I highly doubt they canceled the loan. Suggest that you are detailed oriented and are having a hard time understanding this process. Ask if it might be in both of your best interests to have another broker in the office handle the loan if she feels there is a conflict of personality.
With respect to her fees you should have been able to get a Good Faith Estimate at this point. Just ask for it.
Asking for the brokers contact is suggestive that you are trying to cut them out of the loop. Whether you are trying to do this or not doesn’t really matter. I am certain taht ther are more than a few unscrupulous Buyer that will try and have the broker do all the leg work and then try an end run to get around the broker fee. Might piss you off too if you thought someone was trying to do this to you.
So the bottom line is e big and mature, and speak to the broker.
