Answer
DON'T drive your car any farther than the shop you had the repairs done at. This is not correct and very unsafe. If it didn't do it before make them fix it at no cost. If they refuse call thier main office(if they're a franchise)or contact your lawyer. Sounds to me like they didn't reassemble it correctly. They really could have put your life in danger. Especially if they tell you not to slam on your brakes and you'll be ok. How can you control if you need to slam on your brakes our not. Good luck. You might even call them and tell them to pay for the tow from your house to the shop.
