Advice regarding suing Intuit

Intuit deducted money from my account two months ago for a tax payment. The payment was never made and no one has been able to help. At this point, I have exhausted every support option without success. In fact, the answers I have been receiving are less and less productive, so this situation is somehow regressing. I want to compel Intuit to refund my money through legal avenues. Does anyone have advice or experience with this?
