Well.....hell hath no fury like a pissed off Redhead...

Been working on a deal to sell one of my listings....we finally were under contract, home inspection occurred, we reached an agreement on that. Buyer wanted to put up an FHA required safety railing prior to appraisal.
Seller said ok, but wanted a "hold harmless" letter to cover sellers, myself and my company, and the buyers agent and her company.
I'm working on a report this morning, and the buyer's agent broker calls me....and proceeds to jump on me with spikes....tells me my seller has to build the fence (along with some other stuff) and tells me that I LIED about the price of the house and stiffed his agent on cooperative commission!!!!
SAY WHAT?!!!!
I tell him that first of all I did not lie about anything, we raised the price PRIOR to his agent submitting an offer (5 days!!!) and that I reduced the amount of coop commission I would pay 3 days before we received an offer.
I said we will have to go back to negotiations then....
(Hello....I WORK for the seller!! She says raise, I say how much....she cuts commission, I cut how much I will pay another agent.)
(this is the extremely short version of the conversation!)
It progresses to me asking if he's read the contract and he says it's in front of him....I suggested he read it.

He then says...."You need to stepback!"
(I need to what?!!! Oh you soooooo should not have said that to me!!! particularly after you have just accused me of unethical behavior!!)
My response...."Just who do you think you are talking to? Cause you aren't going to talk to me that way!!"
He then says...."your seller is GOING to do xxxx and xxxx and xxx and this conversation is over!!"
and hangs up on me!!!
The p***k then calls my broker and goes off on her.
Upshot is that I and my seller end up in my broker's office trying to figure out the next steps...we call him, and the chicken shit says he doesn't have time to talk to us.
The buyer's agent then calls .....and she has no idea what this jerk has said to me....and she's apologizing all over the place and said he was wrong (duh!) and could we somehow work it out.
My seller is doing the stuff and raising the price 5k....we'll see what happens. Buyers' are still getting a heck of a deal on the house....plus my seller is paying $5400 in buyer's closing costs!!!
I'm still extremely pissed in case no one can tell......
My secretaries said the guy should have known better than to make me mad.
I have no problem admitting when I am wrong.....but NO ONE is going to accuse me of being unethical or lying about the price of a house or commission. ( I had even told the agent that if she could make this deal work, that I would split the commission 50/50 instead of 60/40) I don't lie....it's too complicated and hard to remember!!
thanks for letting me vent.....
