Update: a week later I finally got my £144 from Rizk. Customer service were somewhere between disinterested and rude the entire time I was chasing up on it. In respect of the next spin I should also have won, I was told:
Regarding your query about compensation, we cannot credit winnings from the bets that were rejected. It’s good to remember that rejected bets are double-edged sword: I have yet to have contacts from players whose losing bet(s) were rejected. Sometimes 2-3 bets can be rejected a row for a customer for some reason, and then it actually saves money, yet no one comes to say they want the bets to be approved.
As a “gesture of goodwill” I was awarded 25 free spins, worth 10p each, which could only be played on 1 of 4 games (none of which I like) and yielded a total of 99p.
