It is extremely difficult for the betting agent to get his money soon considering the low income earnings of the gambler in this case.The gambler's only choice in this context is if he goes and get a loan from the bank which if does so this would burden even further the situation he got and put himself in.That is why gambling is not for everyone and unfortunately the only one to blame is the gambler in this case,most of the blame is on him but if the betting agent just let him play on credit without any contract or any paper or legal agreement then he is the one to have a hard time and probably not ever get his money back.
