Meineke Car Care Center review: Auto estimates not being honored.

My son called Meineke for an estimate. The vehicle had been there before for repair so it should have been recorded in their system. They quoted him a price for the items requested. The vehicle was dropped off and part of the repair was completed, but the rest of the work to be done was now on hold because meineke wanted about $500 more to finish the job. They said that they didn't know it was a 4 wheel drive vehicle and it required additional time for the repair. Meineke had the VIN number of the vehicle from the previous repair and that should have been enough information to make an accurate estimate. They denied that the vehicle was ever in their shop before and they had no record of it. They charged my son for the additional time and gave him a small discount on the additional work after I had to go in there and talk to the manager. The manager (Courtney Fillmore) and technician both lied to my face when I went in to address the issue. I went back a few days later and produced the receipts that proved they were lying to me and was told to return on Thursday 10/26 to speak to the district manager. I returned and met a man who identified himself as the district manager, Dave Riley. He said this shouldn't have happened and that he would get back to me the following day after following up with his manager. I never heard back from him and I've been patiently waiting for his response for several days now. I can't help but think that I'm being Ignored by yet another manager up the chain of command. This is going to escalate before it goes away if Meineke does not respond soon. I've made 3 trips to the shop trying to resolve this issue like an adult and I've been treated like I don't matter by incompetent staff. My son and I will not let them ignore our issue. I've been patient and cordial with Meineke so far hopefully they address this issue ASAP.
