(London, England) — Graham Calvert, an admitted gambling addict, is accusing William Hill of allowing him to open an account two months after asking the British betshop to close a previous account due to his addiction to gambling and is suing for £2 million.

Under terms of its "Self-Exclusion" policy, William Hill can restrict problem gamblers—at the gamblers behest—from attaining an account for as little as six months or up to five years but as the website states, "Unless you request self-exclusion, any account that is simply 'closed' can be re-opened at any time."

Calvert says that despite telling William Hill that he was a problem gambler, he was able to open an account two months later and incurred losses of £2 million, including a £347,000 wager on the Ryder Cup which was considered by many to be one of the largest golf bets at the time.

Among the evidence that will be reportedly presented in the case is a phone recording where Calvert asks to be banned and is told that he will be for six months.

The case is set to begin this coming Monday and William Hill says they will fight all allegations.
