The Pep Boys

So my car was taking some tries to finally start. Lights on the dashboard are working so I know it can't be the battery. I bring it to Pep Boys on Saturday. They substitute the battery. I stop on my way home for gas. Car doesn't start again. I return to Pep Boys.
I leave the car overnight and get called on Sunday for an estimate of 1000 to fix alternator. Alternator get fixed. Pick the car Monday. Get stuck again. Car doesn't work. Bring car back. They say there's no fault. Come pick the car again on Tuesday night. Car doesn't start. Finally they say it's the starter and tell me I have to pay all over again for the part and labor at a discounted price. On the meantime I paid already 150 dollars on uber plus the 882 on the alternator. I'm still waiting to get my car fixed and a refund for the mistake on diagnostic.
