I have to agree with some of the posters. Carrying over negative balances in the current climate is a mistake. Bet365 are good, as far as paying on time, but so are the rest of the UK online bookmakers.
I am not a big European sports betting promoter, but when I got hit with 30,000 pounds negative this Euro, I was quick to dump Bet365. Sorry, but I would rather get 25% with no negatives than 30% and have to work out thousands of pounds in negative balance and pray when I am on the clear no one will come and win again. There are plenty of non-usa sportsbooks which do not carry negative and offer sizable commission.
You guys at Bet365 should get with the program.
