Most debit cards have a pre-set spending limit per day.... I am sorry they took you for everything, but if they got everything in your account then one of two things is happening...
1- there was less than that pre-set amount in your account
2- the fraud came from within your bank.
There are built in safety regulations to all debit card transactions.
Sorry you have had such a problem here on WGT.. they have my information on file and i have experienced no shady dealings on this site.
Peace.
