Brakes stickin after brake job

My brake pedal went to the floor when I bought my 74 Swinger and wanted to make sure my brakes were done right so I was going to get new tires anyway and went to Sun Tire to check brakes.
I had rear wheel cylinder brake fluid leaking from rear drums and pads were cracked and worn so replace pads and cylinders, still pedal to floor so they replaced master cylinder, while driving home brakes were trying to stop the car with smoke pouring off front brakes, when I made it home front brakes smoking and rears hot. Oh and during the rear brake job they turned the drums only to notice they were scrubbing the pads on the inside badly so I bought new drums and still scraping badly on the inside, they put washers behind the drums swearing they were the right pads??
They will be towing the car back up there Friday and Im not sure what to think??
Any ideas???
Thanks in advance
