I dont know why Yupp Tv do not have online cancellation, while online subscription is possible.
I also tried calling 08001899368 for germany and 08000868286 for europe both numbers are not working.
And there is no way to cancel ghe subscription online by myself.
So it is a problem from yupp tv side and I dont want to pay further for this subscription.
It looks like a Trap.
The mail response was that they will respond back within 24 hours, it more than 3 days and still no response.
