Complaint Review: Midas Auto Service Experts

On 7/10/2017 I took my 2002 Chrysler PT Cruiser to Midas because the air conditioner was not producing any cold air. They diagnosed the car for $118.90 and provided a written estimate indicating that there were no leaks and that all that was needed was a refill of refrigerant for $118.90. I authorized the refill and they did it. The car made cold air for several hours then stopped. When I brought the car back to Midas on 7/15/2017, they said the air conditioner was now leaking and needs several parts, and labor for a grand total of $1047.08. Efforts to get a refund for my $118.90 failed. This series of events is wrong on several levels. First of all my understanding is that it is not legal to refill a motor vehicle air conditioning system with leaks. Second if I had been told in the first place that the vehicle needed a $1000+ repair, I would never have gone along with any work as the vehicle is over 15 years and probably not worth $1000. Third, I feel that Midas took advantage of the fact that I have little knowledge of auto repairs and reduced ability to communicate in English, to cheat me out of the $118.90.
