Midas review: poor customer service and refused to complete repairs

I am writing this review as a warning or caution to those who are considering taking their vehicle to this particular shop. I am a nearly 60 year old professional who has been a loyal customer of Midas for many years. I usually take my vehicle to the shop in Mission Viejo but for the past couple of years or so have been taking it to the Lake Forest location. In the past I have always dealt with the manager, Marcos, who was polite, professional and helpful. I wish he was still there.
I recently had an issue with my taillight/blinker not working and I brought my vehicle to the Lake Forest Midas. I was told the electrical plate the bulbs plug into needed to be replaced, which seemed reasonable and the repair was made. Since that plate has been replaced by this shop, I have had to bring my vehicle back several times because the same taillight would stop working. I tried to explain to "Manny" that the problem is most likely a short or loose connection with the electrical plate they replaced. Manny could not have been any less interested in what I had to say, would talk over me and at one point told me they "don't do electrical", although their Whitepages advertisement states they do. The very next day, after one of my several trips back, my battery was completely drained. I tried to explain to Manny there must be a short or loose connection but again he just talked over me and dismissed anything I said. Manny told me I needed a new battery and $200.00 later sent me on my way. The SAME taillight went out again and again Manny was rude and not interested in helping me but said he would have his mechanic take a look. When I picked up my vehicle Manny was not around and the mechanic, who was actually nice and apologetic, told me no one ever told him about the electrical plate they had replaced, so he re-worked all the connections and sent me on my way.
Long story short, taillight went out again and when I tap it with my hand, it goes back on, indicating a short or loose wire. I brought my vehicle back today and told Manny what was happening. Again, he could not have been any less professional or helpful and REFUSED to complete the repairs his shop initiated. I asked for the District Managers phone number and Manny told me he is the "Owner" and they would just have me call him anyway. I told Manny I would still like the number and he wrote down a number that actually connects to Equifax. Dishonest ? Disgruntled ? who knows ... hopefully this doesn't happen to anyone else ... good luck.
