Perhaps a bit overkill and I personally think someone doesn't need to go to such length [which I consider a rather private matter] just to prove their residency status, but what do you think about attaching your recent grocery receipt? One from a convenient store that happens to be around the corner where you live might be even better.
Thank you for your input, I have been away and have just sent the email to the Rollbit team, please see below the email I sent, I also attached a recent restaurant receipt in LUX as you suggested.
"Hi Rollbit team,
Apologies for the delayed reply, it seems like my statement might have caused some confusion. I am not residing or living in the UK (or London) and as I stated on my previous email this was a mistake on my part as I thought I would be able to withdraw the funds without completing KYC.
On this regard, I am willing to provide more than enough personal information to prove what my living condition is (going far and beyond what would be expected in a KYC process). Please find attached the following documentation that proves that I am still living and residing in Luxembourg: payslip for July, employment contract, Spanish ID, LUX residence permit, social security card, utility bills as well as tenancy agreement (and a recent restaurant receipt, the bank is also addressed to Luxembourg). Being employed in Luxembourg, as well as proof of actually living there through utility bills, tenancy agreement, payslips and residence permit will prove beyond any doubt that not only was I living in Luxembourg throughout the use of my account, but that I still continue to live here.
Let me know if you need any further clarification, I understand this is ample proof of my current (and previous) living condition. I am also happy to carry out an enhanced KYC or show you all of this documentation live."
I hope this can get resolved soon this way, as the proof I am providing is irrefutable. In case they come back with a negative reply, what could be my next steps?
