AutoNation Chevrolet West Austin

My truck has 21000 miles on it. I took my truck in for an oil change and for the service dept to advise on fuel filter and air cabin filter change. my advisor gave me a price of $120 for the oil change, later he texted me and mentioned that the fuel filter and air filter would be a total of $180. I gave him the okay. when i picked up my vehicle the total cost was $630 double what I was expecting. my advisor pretended to not know who to read the information on the computer and brought an other advisor to carry out the theft. I will never do business with Auto Nation again, i don't trust them, they probably didn't even do any of the work just reset the readings to read everything okay at 100%. The advisor is a >>>>>>>. the other thing i called to check status of the work and he said that it had been ready for a while but was too busy to call me.
