2017 Volt - Onstar not working and can't get it activated

[mtv___]

I just bought a 2017 Chevrolet Volt Premier.
I tried to get OnStar activated by pressing the blue button but got no answers.
I tried to call pn the phone to get it activated, but the person told me i have to do it with the blue button in the car.
I tried to activate it online, but even after i purchased an OnStar plan, i still can't get it activated in the car.

So i tried it again with the button in the car and after waiting for 5-10 minutes, someone finally answered.
So i tell the person i want to activate my Onstar Account and she tells me i have to do it with the blue button in the car. So i tell her that is what i just did and we are talking through the Onstar button in my car.
But even so, she tells me she can't activate it...

If a phone call, a web site or even the blue button in the car can't activate OnStar in my car, how am i suppose to activate it?
