My main gripe with coral.co.uk is the site itself - a nice clean layout but very glitchy. The same is true across all digital platforms including mobile site and app.
Also, I have been finding bets placed in shop via connect card are taking longer to settle of late and have had to go back out to the shop due to lack of support online.
Anyway, some positives: sports promotions are generally good, and better than some of the competition, as are odds on big events.
