Midas

I've gotten in oil change from Midas about a month ago and as soon as I left the building my oil leaked completely out, the car started to smoke up leading me to go back to them. Come to find out my oil cap wasn't on due to them and because of that happening my car wasn't able to start. Midas told me it's was the timing belt and tried to fix the problems, it caused me to be able to leave Midas but a couple weeks later I come to find out I had a small leak in my oil causing my engine to lock up so basically my car isn't working now and they are not fixing it
