Rural King Huntsville, AL. review: Tractor repair

I live in Fort Payne AL. About 2 years ago, I purchased a used 2017 RK55SSC tractor with just over 400 hours on it. Since I bought the tractor I've been doing business with Rural King Huntsville AL location to buy my parts and filters for my tractor. The tractor started losing power and not starting well so I contacted Rural King Huntsville AL location and set up an appointment to bring my tractor in for what I thought would be a quick adjustment and service. I brought the tractor to them a little over 7 months ago now and still haven't gotten it back yet. After about 3 months of calling and trying to get an idea on some kind of time frame as to what was going on with my tractor Chad finally told me that 2 of the injectors were bad and they were having a hard time getting the injectors from Rural King so I waited about a month and called back. Chad told me that "I still had no idea when we will be getting the injectors in here" so I asked are you guys 100% sure that the injectors will fix the problems with the tractor because I need it back. Chad said that they were certain that the injectors would fix the problem with the tractor he also told me that they had a mobile technician to verify their findings. I ordered a new set of injectors from Pensacola injectors ($2300) took the new injectors and hand delivered them to Hayden (technician) on April 30, 2022. I waited for about 2 weeks and called back it took several attempts (with no return calls) before I finally got back in touch with Chad, he told me that things were going crazy because he had been out for a week but assured me that " we're going to get it fixed next week, for sure. " That was at least 8 weeks ago. The store manager (Branden) called me about 2 weeks ago after posting a complaint on Rural King’s web site, and he said he would get it resolved but now won’t return my phone calls. Thank You!
