Consumer Direct Savings Offered me a chance to win a coffee maker for $5.95. Then they charged my credit card $89.95 a monthe saying that I signed up for a subsription. Internet

I was told that I would be given a coupon code worth $125.00  to use at their site www.consmerdirectsavings.com but this is an invalid web site and the coupon code is also invalid. Then when I get my credit card statement, there is a charge from them for $89.95. Which they say is a subscription.  I was able to get them to cancel the subscription but they won't refund my $89.95 which I got no goods or services for. I told them this was a scam and fraud. They hung up on me twice.
