Web.com Charged over $10,000 to my American Express acct after services were terminated and won't refund the ripoff Jacksonville Florida

Web.com was hired to improve web visibility and SEO optimization. After 3 months of absolutely no progress or benefit even their acct managers (they went through at least 3 in same time frame) admitted to the failure. They were given written and verbal instruction to terminate their costly but ineffective "service".For the next 7 months they continued to bill my American Express acct. I became aware of it when my bookkeeper was preparing a tax report. At that time I rasied Cane and Web.com (in particular their corrupt finance supervisor Christine Rodriguez) continues to refuse to issue a refund for the money they stole.
