If your guy who set the dish up said you was getting 99% at the dish with is meter, then went inside to connect your box and had no signal. Why did he not use is meter on the cable at the box end to eliminate everything to the box. Thats what I don't understand here.

If you have an android phone then download the app called satellite pointer.
It gives you line of sight info to see if the sat position is obstructed ?
This thread brings back memories of me trying to install my own dish kit without a clue what I was doing last year.
Through trial an error here is how I fixed mine. (although I didn't have any obstacles in the line of site)
I used dishpointer.com for a a rough line of site for my satellite. I used the line on the map to see roughly the direction it was going and used a reference point on the map (i.e a straight line to my neighbours chimney.)
I then used a cheap ebay signal meter to get a more accurate direction.
Then I went to my box and I had no signal. noooooooo.
Re-ended the cables. Nothing.
Re-ended the cables again. Nothing.
Youtube time.

Houston we have lift off. Finally on the third attempt I had signal. It was about 70% on bbc so I was pretty chuffed with myself that I some how managed to set this up on my own with no knowledge whatsoever.
Then I tried watching other channels at it was breaking up a glitching like mad.
Through further research I found there was many apps you can download (android) to fine tune your dish while up the ladder while showing the signal of your box on your phone. Who needs an expensive satellite tuner.
Highly recommend Dmsatfinder and Enigma Signal Meter(satfinder). Just make sure your adjustments are absolutely minuscule while fine tuning.
The above might not be your solution, but it might help in your trial and error quest to find your solution.
And if it wasn't for all these initial problems I wouldn't have been on this forum now. My enigma2 skinning journey would never have happened and I would have done what a large majority of people do. Set it up. Watch tv. end of.
Instead I spent all the time my box was working just reading all the posts on this forum and now I am extremely knowledgeable about these boxes....and now I pretty much live on this forum. Its a funny old world.
Quick update...you could buy a cheap sat finder from ebay and check it yourself at the cable before it enters your receiver. you will need to make up a small length of 'patch' cable though with two f connectors.
downside to that though, is you cant alter your dish from the front room and it might show good signal strength, but on the wrong satellite !!! that's why the suggestion to try signal strengths/channel searches with your tuners not fixed to astra 28.2 ( I think in tuner set up, it automatically scans for all signals) quite often when im in france, I pick up a brilliant signal strength on the meter, only to find its the wrong satellite !!
just to confirm you do have the cables in the correct configuration to the back of the zgemma?
