The punter, whose identity is known to the Guardian, opened an account with Bet365 on 16 April and deposited £30,000 with the firm the following day, when she placed a series of bets on horse racing and lost £23,000. She received an email from Bet365 the same day, which stated that the size of the maximum bet she was allowed to place had been increased.
The following day she placed further bets with the remaining £7,000, winning a total of £47,000, which raised her balance to about £54,000. The same day she was informed via email that in future her account would be restricted to a maximum stake of £1 on racing bets as the result of a “trading decision”.
