National Tire & Battery [NTB] review: service on my brakes and rotors

To whom this may concern I brought my lexus in 2012 is350 august 4, 2019 to get a few services done such as an oil change, tires, brakes, and alignment. I first ask if they had any promotions and leo curtis stated to me that they didn't have any promotions. Which was a bold face lie when I did some research they had a few promotions online. So later on they had to adjust my bill. Secondly after driving the vehicle for a week I noticed that my brakes was making a really loud noise so I followed up with leo curtis. I was really nervous because of my brakes felt like they wouldn't stop so it was a major concern for me. And safety issue. I spoke with him twice and they still can not fix the issue also after speaking with the district manager he was really not concerned at all and never follow back up with me. He stated to me bring the vehicle back up and he credit me some money to my account but the issue is still not fixed my brakes are still making a really loud noise and feel like they won't stop at all. If someone can please follow up with me I will gladly appreciate it because I felt like I was taken advantage of I spent well over $1300 to get the service is done and to this day the brakes are not done correctly and my will alignment. This service at this location is horrible I even asked the district manager where they certify. His attitude is very nonchalant and should not be working for the company. Also if things are not fixed I will file a lawsuit. Mr, little [protected]
