Chatter and Hiccups

[SSKNMachete]

Recently after I got my car back from a dealership to get some cosmetic damages fixed. Shortly after my clutch was grabbing in an extremely limited range and whenever I accelerated I had a chatter like the pistons were banging around. And I'll get hiccups every once in a while when accelerating. Anyone had similar issues? I'm really trying to keep my car in top shape but it seems like every time I turn around there's something on the verge
