I just got confirmation from my UK provider that my location will show in the UK when I am connecting from LUX.

While you are in Luxembourg and using your mobile data, getting that screenshot of whatismyipaddress.com to show the IP address will be an asset to you regardless of (and in addition to) the emails various telecoms have sent.
Well said.
Seems like Razor, as in any other accusation he replied in, doesn't deem it necessary to follow up stuff. Rollbit is always right and the customer is 100% at fault, always. Nice approach they are presenting here.
Though my opinion means nothing, Rollbit certainly could have handled this matter in a way that would have seemed more sensitive towards the dilemma the OP is facing.
And about the signature guys, this also jumped out for me. When I represented BC and thought they handled the case wrong I also called them out and even spoke to the representative in private to find a good solution for both sides.
Even the rollbit campaign manager gave me an unpleasant feedback for calling the site out, basically feedback abuse.
Can you provide a link for where/when you called Rollbit out and as a result received the feedback abuse? I have known Hhampuz for many years and have never associated any sort of feedback abuse with him. He is one of just a tiny number of forum members that I would trust in real life.
Keeping that aside, if any casino or gaming website is doing the wrong thing, I am sure many members including those that wear signatures associated with them will ask questions and take a stand. Even though many Rollbit campaign participants have not been posting in this thread, the ones that did seem to have consensus that Rollbit are treating the OP unfairly. I could be wrong but I do not think there is an automatic conspiracy by default between the websites promoted by signature participants and the wrongdoings of those websites. Having that mindset means almost every member in this forum is corrupt when the reality is to the contrary.
