Turbo Tax refusing to refund me despite not filing with them

I was charged around $88 by TurboTax for the Deluxe version and the state filing fee, not realizing they would charge me immediately. After deciding to file with FreeTaxUSA since it was more affordable, I found out that TurboTax is refusing to refund the $88, even though I didn’t use their service. Customer support has been completely unhelpful, and when I disputed the charge with my bank, they said there was nothing they could do, as TurboTax is insisting it was a valid charge. I will never use TurboTax again, and now I'm out $88 for a service I never even used.
