prada, inc. smokefreely.com charged to our credit card without authorization. scottsdale, Arizona

daer sirs;
The following company, Prado, Inc., aka smokefreely.com has voided their contract by charging unauthorized money to our credit card.  The original charges should have been 7.95 and the final charges totaled over 282.00 dollars.  We are working with the bank to charge by this amount for services not recieved.  We are also putting a not allowed to charge stop on this account.  So we can stop future charges.  Please help stop these thieves before they can steal from some one else.  It's companies like this that give the internet a bad rep. plus cost us indirectly by ripping off the credit card companies.  But this is a contradiction in terms.  By mentioning ripoff and credit cards in the same breath.
Thank you in advance for your help. scott
