They advertise that you can cancel subscription any time...I used their service for a couple of months and then decided to cancel. They had just charged me on a Saturday $100 for the coming month and I asked them to cancel my subscription following Monday morning...they refuse to re-emburse my $100 they charged for service they did not provide...in turn they are telling me that next time I want to use their service, they will give me $100 credit.
