I've just had to file a complaint with the Gambling Commission.
I tried to place a ten-team coupon with 9-folds, 8-folds, and 7-folds, but the site placed my bet as a single tenfold. I attempted to correct this, but the same issue occurred.
When I contacted support to request a refund for these erroneous bets so I could place a new one, I was accused of lying. I recorded the error, so I requested my account ID to report the issue to the Gambling Commission. They refused to provide it.
These actions are extremely concerning and not what I would expect from a legitimate company.
No reply.
