Bad experience with Muller Honda

We received the recall notice in January 2024. I called Muller Honda. They told me that they didn’t have the part and would let me know when it became available. I received a second recall letter in March and called them again, but got the same response. I waited for over half a year without receiving any call from Muller Honda, so I called them again today. I was told they still don’t have the part. The problem is they never called me back regarding the part.
