Discover Card ripoff charged my account Discover Drivers Premier Salt Lake Utah

On 23rd of November 2001 Discover Card charged my account $79.95 for Discover Drivers Premier membership. Since I have never authorized any company for this membership I called tel # provided in the statement (800) 995 3000. I disputed this charge and requested to cancel my membership. I've been promised over the phone that charges would be reversed and I will be never billed again. However I have been repeatedly charged over and over. All together I have been charged for $419.75 plus interest that I paid on those charges.

I have been billed for

23rd of November 2001 $79.95
19th of December 2002 $79.95
19th of December 2003 $79.95
19th of December 2004 $89.95
09th of December 2005 $89.95

After numerous calls to Discover Card customer service with demand to credit back all unauthorized charges Discover Drivers Premier membership, in December 2005, Discover Card credited back last charge $89.95, but refused to credit back other four charges.
In telephone conversation Customer Service representatives repeatedly lied to me trying to convince me that I actually authorized some telephone marketing company charge my account for Discover Drivers Premier service. My requests to provide the name of this company or any confirmation that I authorized anybody to enroll me to Discover Drivers Premier membership was in vain.
