Meineke Car Care Center review: Car repair not done and charged 1554.10

I first went to Meineke of Gastonia on Saturday 5/22/21. My complaint from my car was that when I reversed I would hear a loud popping sound, and my air was not working, also my steering wheel would shake driving. I left my car and when it was supposedly ready the tech called me and said my shocks and alignment needed to be replaced and that my air was not leaking and they would add freon. I gave the go ahead for the work to be done. Which came to about 1700.00 dollars. I did not have that much cash, so I was approved for a loan through easy pay finance for 1500.00. The total being 1554.10 I did drive my car home, I didn't notice nothing to crazy, because I live less than five minutes away. But on Monday, on the way to work, nothing was working as before, my air was still broken, the steering wheel was shaking profusely, and I could still here the popping sound when I reversed my car. I immediately called the Meineke and got the answering service, and left a message about my car. I also called again on my lunch break and spoke with the lady who I was helped at front desk on Saturday. She told me they closed at 6, and I could not make it in by that time to come back in because I was working in Concord that week and would not make it in time. So my only other option was to come in the following Saturday 5/29/21 and get things rechecked out. So I go back the Saturday and leave my car. When the tech calls me back he says oh we had to change the air filter it was dirty, and you need a lower control arm because that's the popping sound and its gonna be 1000 bucks. At this point Im done being scammed. I say just fix the air, which I'm not sure why they charged me and additional $26.00 in the first place, because thats what I was charged for originally in the 1554.10 the week before. But I pay it and leave, because at this point I know that they just wanted to scam a single women who they thought was stupid and would just let it slide. But I want to make everyone aware that this is a scam, I have receipts and proof, my cars still broke 1554.10 dollars later. And I need help getting some guidance on how to get my car fixed or refund of some sort. Please help me.
