They may have an arbitration clause, in which you agree to not litigate. 4D chess.
That would not hold up in court. At least not in European court. Consumer law trumps EULAS and its illegal to put arbitration terms in consumer contracts.
Take a look at what's happening with AT&T, arbitration in the USA. Consumers have lost a lot of their "rights"
they don't need to justify anything. Their platforms, their rules. You signed your rights away when you clicked yes to the EULER.
Of course, you can litegate, but then you'd end up costing more money than you can gain, and probably no one will find it worth the hassle.
