i opened a Dunder account and after depositing 2350 to gain the bonuses i then placed bets after 15 minutes of having most of my bets rejected and losing 40p (not a massive amount), I became frustrated and decided to take my money back. however even though they will be putting the money back to the card it was taken from they are demanding i complete a statement of wealth. Why do i need to do this after 1 bad experience?. is this a LEGAL necessity?. what are my rights regarding this?. any and all advice would be greatfully appreciated
