All these **** new bookmakers on oddschecker can't be trusted.
But 138Bet is one of the largest and long-established Asian bookmakers. And 12Bet has been around for a long while; I had an account with them some years ago and never had any problems. They also have reasonable scores/reviews on SBR ( okay, okay, I know SBR is becoming a bit worthless with it's practice of taking advertisement money from bookies, but all the same......). So people can be excused for being a bit more trusting of them compared with the really blatantly scam outfits.
I have to agree with Luke; this fiasco has all the hallmarks of a serous cash-flow problem, or a case of simply running out of funds to honour the bets.
These four books under the one company umbrella offered advantageous Chelt sign-up deals that attracted thousands of matched-bettors in their droves. These sign-up "come-ons" were widely touted on matched-betting paysites like TGT and PA (the notorious PA has over 33,000 Likes on Facebook alone). The likes of PA promises easy-money income to students and housewifes who mostly have no clue of horseracing or the basic principles of betting. They are naive and incompetent, and they signed-up by the boatload because they were advised by PA to do so.
So, 12Bet et al were simply overwhelmed with new accounts. Then the results went against them -- 1st and 2nd favs winning disproportionately etc. The £25 free bets also won, and the die was cast.
The result is close to carnage out there. The majority of new sign-ups were definitely matched-bettors encouraged by PA and such like; these matched-bettors have not only been denied their wins on 12Bet but have also lost the Lay side on Betfair (so, broadly, people who say they have not been paid, say, £1,000 by 12Bet are, in effect, down twice that amount).
Where will all this lead to once the dust has settled? Hard to say,I guess. If Xela Holdings just refuse to pay and pull out of the UK market then it could spell the deathknell of "matched-betting for the clueless" and the demise of the likes of PA ( which would be a good thing, surely). Unfortunately, if 12Bet get away with it, it may encourage other mainstream books to follow a similar policy regarding bonus's and other offers that result in wins.
And, if the Gambling Commission don't get a grip on this particular issue fairly pronto, then whatever credibility they have will vanish.
