Hi, I am Dave, I will help you with this.
Driver Support is a 3rd party website that has no affiliation to Microsoft, and they make it very hard to unsubscribe to their services.
Log into www.driversupport.com then go to your account page and from there, you should be able to cancel your payment to that website.
Also, it would be a good idea to block the payment at your bank.
Drivers are always free and you can download them from the support page for your PC on the manufacturers website
