Air Bag On-off Switch problems of the 2013 Volkswagen EOS

Takata recall on 10/19/18 I took my car to the dealership so that they could install the new airbag inflator kit due to the recall. A few days later I noticed my horn was not working. I returned to the dealership on 11/9/18 only to be told I need to replace the entire airbag because the brackets connecting to the airbag are not sending a good signal to the horn. However I went online and one of the items clearly called out with the recall is "do not pull on the horn switch feed pigtail wire to disengage the connector from the driver airbag housing or to disconnect the horn switch to steering wheel wire harness connection. Improper pulling on this pigtail wire or connection can result in damage to the horn switch membrane or feed circuit. " although I have a warranty I was told my issue is not covered and that I need to pay $598. 00 pre tax to fix the issue. Based on what is documented online it would seem an error occurred with the installation of the airbag inflator kit impacting my horn. I did ask the dealership what other issues could this cause and if the airbag was impacted they explained since the airbag indicator light was not on nothing was wrong with the airbag. However the indicator light was not on with this recall either but something was horribly wrong. I'd like any assistance to confirm this horn issue is not related to the replacement dealing with the takata recall. Thank you.
