Yes there are two bolts (1) that hold the caliper in place. They thread into a long "flat sided" head bolt.
"Two" are used for each caliper.
Here is a picture/sketch of the setup

THE TWO "DISC CALIPER BOLTS" #17 HAVE A FLATS ON EACH SIDE OF THE HEAD THAT LOCK THE BOLT IN PLACE TO KEEP IT FROM TURNING. THE 2 CALIPER ANCHOR PLATE BOLTS #16
THREAD INTO THE DISC BRAKE CALIPER BOLT #17.
THE "TWO" CALIPER ANCHOR PLATE BOLTS #16 ARE TORQUED DOWN TIGHT !!
YOU MENTIONED THE BOTTOM CALIPER ANCHOR PLATE BOLT IS MISSING. THE MISSING BOLT IS "ABSOLUTELY" WHAT HAS CAUSED THE PROBLEM !!!
If you had the brakes done at a shop someone screwed up "BIG TIME". What happened has caused damage !! Metal shavings,brake fluid etc.
I would take it back and tell them you want everything replaced "New". They will probably give you a song and a dance and say it was not their fault and the bolt was in place when the job was done. Take them to small claims court.
Oh my aching A$$ ...to put it mild !!
"I wish I could state my actual words I am now thinking about this". What "you" are thinking reading this.... we probably are using the same "choice words" dictionary.
This could have been much,much worse...you or someone else could have also been injured!!!!!!!
