Well it's actually hard to help you since even we try it seems like rollbit is resisting any arguments.
They repeatedly said you "admitted to live in the UK" but when I asked you weeks ago about that you said that you never did.
Sure it should not matter for this case if you live there now when the actual gameplay was made somewhere else.

I do agree with rollbit about 1 thing though. It would appear strange if there is actually not 1 single LUX IP in your history. Maybe you are very strict about your habits and really only play with the phone provider IP but even I for example sometimes use the wifi in my gym or some hotel or whatever to check my account and claim some bonus or whatever, not necessarily for gaming.
