Hi Steff72
Welcome to the Community, I'm really sorry to learn about the problems you're experiencing with your On Demand service.
I've been able to locate your account to take a closer look at this from our end for you, I can see that there are some intermittency issues with On Demand in your area at the moment but that shouldn't be causing you to not have any access to the On Demand part of your service.
If you've still got no access whatsoever, get in touch and I'll take a look at escalating this from our end for you.
Take care
Craig
