Any way I can find out who easy and how I can get my money back from 'easysearch4cash' and stop them from taking money via my Visa Debt card?? This has happened a total of 3 times:

2nd October 2009 Aust: $68.70
1st Sep 2009 for Aust: $71.40
1st Aug 2009 Aust: $73.45

and now I see they are trying to take a further Aust: $66.90 !!! as of today 1/11/2009

I can't afford this and have no idea how this company/person is? I have never authorised this to occur.

please please help!
