NHTSA Complaint #11702625 — 2012 FORD F-150

i dropped my ford truck off for a recall that was done only three months ago and it had an extended warranty (Recall campaign number 19S07/19V075 sudden downshift powertrian control module programming) with it but it didnt fix the problem. when i picked up my truck after them keeping it for two weeks and telling me they had no loaners, they tried to say nothing was wrong with my truck and tried to charge me a $169 diagnostic fee and never even fixed the recalled downshifting transmission problem. But when I am driving it will just downshift almost causing the truck to jerk rapidly to a complete stop. This has almost caused an accident and ford wouldn’t even try to fix it and because I refused to pay for a service I did not request they told me to never come back. My appointment was made online and clearly stated the info about the recall repair not being done right on July 12th 2025. So now I don’t know how to rectify this transmission problem
