I am not doing anything suspicious - just betting on a few football matches that seem like they are profitable, and I am betting from Ireland where it is legal.
Has anyone experienced this before - really don't want to have to give my personal details across to a gambling company!!
Did you carefully read the ToS before registering on the platform? There is a rule that they reserve the right to ask KYC at any time, and I'm assuming they asked KYC from you because of a rollover requirement. This means that each user must wager at least 3 times the deposit (for sports betting), and only after that, the withdrawal may be approved. Anyway, if you didn't break the rules, you should not have any problems with KYC because Betfury can be trusted.
