The only way forward is to make a better offer on the name in my view. Agee the stuff about sorry for the phone call could be put in also.

A day late and a dollar short.

I have made fair and reasonable offers for this domain name
Yeah but this guy may not be a domainer who knows the market and if he is a mainstream guy running a mainstream business he probably thinks that if it ain't 5 or 6 figures he is not going to even turn his head.
Maybe your, what I assume, 3 or 4 figure offer was actually insulting and why he treated you harshly.
Also you need to remember just because you have an offer for him doesn't entitle you to his time or to call him whenever you want.
On top of all that you are potentially looking at this all the wrong way. The fact this that guy owns this sweet name, and has done nothing with is a god send for you.
If he had not of registered it and taken it off the market many years ago then someone else with a half baked idea would have bought it and it wouldn't not be available for you today.
Or if he had of done something with it and it was generating him a real income then his price expectations would probably be five times as high and out of your price range.
Instead, and luckily for you, there is a great domain just sitting there with an owners who probably doesn't know what to do with it or its value...
So maybe if you dropped the entitled attitude and tried to work with the guy potentially offer him an HONEST education on domains and domain values (at a time that suits him) and then showed a bit of courteous by offering him more than fair value given that he clearly hasn't come to the market looking to sell.
Hell maybe, he knows it's worth a boat load and he is in the industry and never going to sell, but at the same time he's not a tech guy and is he's not looking to sell as much as he is looking for a business partner to develop the name.
And at the end of the day if you have a really good business model for the domain that you are confident is going to make you money then just offer him a price that is a better return than he could ever hope to achieve from the domain himself...
That's the way capitalism works. The assets flow to those that can afford to pay more because they can leverage them better.
If you just want to throw up some thin MFA or affiliate piece of junk then leave the guy alone he is clearly waiting for a big player to come along and you are just wasting yours and his time.
