AutoNation review: auto collision repairs

My 2020 Landrover Evoque was involved in an accident, I contacted Landrover Ft. Lauderdale on Copans Rd. Spoke to GUs Germi, Collision Manager who assured me I would be in good hands and he had no inventory for repairs for any other vehicles and that my repairs would be completed in a timely manner, I delivered my auto there on June 10th and it was not returned to me until August 16th. OVER 2 months for repairs, during that time I did not here from Gus Germi even though I left messages. I spoke to Omar at the Autonation Collision dept. He was in charge of overseeing my repairs, He made SEVERAL errors in ordering my parts for my vehicle therefore causing much delay in making the repairs. I escalated my issue to the Manager of that Autonation location, Renee Estevez. He too never returned my calls in a timely manner, he also Lied to me ..as to what was going on with my auto and how he intended to resolve it. Over the two and a half months it took to repair my vehicle, I had to pay for a rental, make my car payment, pay for auto insurance, put up with lies from the upper management etc. I now have my Auto back, a brand new 2020 Landrover Evoque, and guess what? I have mix match tires on the auto. The car drives rough, If I have a flat tire I am unable to purchase another tire to match. So my life and the life of others is in danger, I want this resolved or I am going to have to seek legal advice. Please contact me for additonal information. I feel there is no resolution in sight because absolutely no one will return my call, not even the Autonation complaint line.
I want my tires corrected, A refund of my car rental and a refund of the 3 car payments I made while my car was supposedly being repaired.
