Tire Works Total Car Care

On March 2nd I had my car towed to tire works at 445 west centennial parkway in north las vegas for a flat tire only. There was nothing wrong with anything else on the car. I received a phone call saying that they would replace my tire bit had to order a different one and that all of my tire sensors were not working. Mind you, all of my sensors worked before the car arrived there as that is how we knew we had a flat to begin with. They changed the tire and we refused the sensor replacement. Sensor light has been on since. On April 19th we had the car towed to the same tireworks for another flat tire... was hard to tell something was wrong with the tire this time because of our sensors being out of order. They once again replaced the tire and when I went to pick up the car the check engine light was on. I immediately went back in and had them check it out as it was NOT on before it arrived at their shop. I am really frustrated as now not only am I having to replace tires I am struggling to get this check engine light off and have to figure out what to do about my sensors that worked perfectly before my car was towed to their shop. Of course when I broight these situations up to the people working at the tireworks they had excuses as to why the sensors didn't work anymore. Excuses like maybe all the batteries died, like really, at the same time and just so happens the car was there. Really frustrated. Tried finding a number to contact corporate and couldn't find a number. I will not let this go as we are very good at upkeep with our car (2014 nissan sentra with under 100, 000 miles). Please advise.
