Business ProfileforToyota Subaru Scion of Morristown

We brought our car to Toyota of Morristown service with the check engine light on. They diagnosed the issue and charged us for the diagnosis and the part, which was backordered possibly up to six months. This was not a crucial part, I think a thermometer casing or something. We paid $350 in March, 2022 for the diagnosis and the part.They never called us back. We took the car elsewhere for inspection in February, 2023 (the dealer doesn't do inspections). It failed due to the check engine light. and the mechanic diagnosed and replaced the part. We paid this mechanic the full amount for a completed job. I called Toyota to discuss a refund for the diagnosis, which was correct, but had to be re-done to pass inspection. The first call they told me I needed to speak to *****, (who checked me in a year before). He didn't return my call and I called again. Again, no call. On March 24, 2023 I called again and same story. Today I said I'm calling back in 45 minutes if he doesn't call back to speak to a manager. He didn't call, I called back and he finally got him on the phone. He told me I needed to speak to the parts manager, but he couldn't find him. He would not give me his direct manager's name, I asked **** times. I told him I'd hold while he looked for the parts manager, he hung up.I called sales to talk to someone else, who transferred me back to service that finally gave me **** (*****'s manager). She got ***** the parts manager right away. They offered me a refund on the part less a restock fee (about $60 total). I declined as I had to pay for another diagnosis and they got the director *** on the phone. We spoke for about 45 minutes. It was contentious, I was fed up and he called me an extortionist for telling him I would file this complaint and put very reasonable low ratings on Yelp and ******* He admitted on the phone that they got the part 6 or 7 months ago & did not call me back. I want a refund for the diagnostic as I had to pay someone else to do it.
