Has anyone ever heard of a bookmaker limiting someone's bets both over the phone and on the internet even though they constantly lose?

The explanantion I received today from Sportingbet was that I had bet on some prices that had moved out eg outsiders, and now my bets were a maximum of $50- over the phone and up to a maximum of a $10- loss for them over the internet (last attempt was $15- on a favourite in soccer at $1-90 which was knocked down to $11-, WHAT A JOKE)

If I have lost $550- since the start of this year in this account, what is the problem? Is this bookmaker not in the business of making money or is it that they are unable to calculate a market and change prices quick enough? Have I not lost enough?

The only reason I had an account with them was because they have a reasonably comprehensive soccer market but they appear to be a far cry from their overseas namesake.

More than 95% of the time that they have limited my bets before or knocked them back, the selections have lost meaning they have won a lot less from me than they should have. Thus money has been saved or given to other bookmakers or TABs. With the above stats, you would think I should take the tip that they are giving me, I am not good at punting but one continues on.

Sometimes I like to put $60- or $70- on a "Draw" in soccer and these limits make it impossible to get a good thrill out of a game.

I also have accounts with International All Sports, Centerbet, Luxbet, and TABCorp, and none of these have ever limited my bets (last week a bet of $230- on Centrebet - NO PROBLEMS).

What gives? Can anyone explain it?

The male staff at Sportingbet, who I believe may be bookmakers in their own right, all have a very indignant attitude believing they know what is going on but it escapes me. One would think that if a price goes out, then no one is betting on it and they would welcome my dollars to help balance their books but it must be a case of them being a very small betting organisation and $60- on a draw at $3-20 is enough to scare the pants off them.

Anyones thoughts on this matter would be greatly appreciated.
