a few months ago i was asked to join in an art contest. i did so using my 
visa debit card. it was only $50. round about the beginning of june (this 
month) 500 was pulled out of my account by them. it took two days but it was 
put back via money transfer after i raised holy hell. i was given the 
explanation that their computer was doing the quarterly audits and went hay 
wire. they were very polite and prompt with getting back with me and such... 
i did get my money back, but it was very nerve racking. i don't plan to do 
business with them ever again. but this is the only experience i have had 
with them.
