Air Bag On-off Switch problems of the 2005 Ford Ranger

I received a notice on 7/16/15 that my 2005 Ford Ranger was affected by recall 15s22. I then received a notice on 12/7/15 that the repair parts were becoming available. I was in contact with a local Ford dealer's service department, and after the repair parts arrived, I made a 2/15/16 appointment for the repairs. The name of the dealer that performed the repairs is sunset Ford. On 2/15/16, the repair was made on customer number 71758, and invoice number focs185790. However, after the repair parts were installed, the airbag warning light appeared on the dash. This hadn't happened before the repair was done. Then there were e-mail communications between the dealer's service department, and a Ford agent. The agent stated that this isn't the first time that this has happened, and explained that a fuse needed to be removed to DE-power the system, and then returned. The service department tried, there was a battery disconnect, and a fix didn't work. A switch, or circuit, or something else isn't working. The cost to fix the new failure is $253. 99, and Ford won't cover it. I declined pay for this new failure, and left the dealership with an airbag dash light that initially blinks, and then stays on. This vehicle may be more unsafe to drive now, than it was when it was initially taken-in for safety repairs! 1. Did Ford provide adequate training for repairs on recall 15s22? 2. Did the repairs for 15s22 create a failure for something else? 3. Is there something else that should be recalled for repairs, such as the root cause for the current condition that is causing the dash's airbag warning light to go on? 4. Is Ford doing something to try to create extra business for its dealerships that's at the customer's expense? 5. When will Ford, or the dealership sunset Ford, get my truck's warranty-related safety defect corrected, at no expense to me?.
