I recently called about a problem with my vehicle, and was told to take it to someone for evaluation, Took it to Ford Dealer and was told had transmission problem. Was also told repair of any kind was denied. Due to low fluid, claim was denied. How Do I check for low Fluid, Transmision is a Sealed System, do Dipstick no dashboard light warning. Called to speak to someone, all previous E-mail and phone No's, non-existent? Did I purchase a warranty that does not work, If so how can I get a refund of monies paid so I can get vehicle fixed? 

Reason given was,Transmission low fluid", that why I took it to Dealership,to find problem of slipping shifts. No way to check Trans fluid, Sealed system? Did I purchase a warranty that does not work, If so how can I get a refund of monies paid so I can get vehicle fixed?
