Get your taxes done using TurboTax

Turbotax correctly identified that I overpaid FICA taxes by several thousand dollars last year, and then failed to submit that information for a refund.  Despite paying for "Max" service, after multiple attempts I have not been able to get anyone on the phone who understands what FICA taxes are and / or graduated high school.  Could someone please help direct me to a someone who: (1) knows what Social Security is and can understand / escalate the product issue, and (2) help secure the additional refund that I am owed.
