This is normal, to them they often pay commissions on the number of services performed so it pays to do quickly.
When we did the renovation of a friend's bachelor apartment was literally identical, he turned off the gas, came in and twisted the keys, turned the plug , put the meter in the bag and out. He didn't even check for leaks because he knew we wanted to cut off the pipe in the apartment.
The meter was in the kitchen it was arranged yet with the administration to cut off the riser , the valve was already there so the problem was tiny.
Then it went easy, we took down the pipes in the house ourselves and shortened the pipe to the riser because they did not agree to cut off the apartment from possible ever access to gas. We put a blanking plug fortunately there was an elbow right at the entrance to the apartment it was not necessary to thread. Then a small pavilion and you can not see the cap with a piece of elbow.
Easy but paperwork at every step and waiting for a decision, in our case the operational time is 8 days.
