There is no thinking or guessing to answer all these vehicle questions

You either have the knowledge to work on them,find & then
resolve issues or you don't,in which case you pay a repair shop to so.

You only have to bleed the brake system once

You either have a hard brake pedal or you don't

You need two people to bleed brakes,it is a pretty easy job & you
need to bleed all 4 corners.

So you have air in the system,it wasn't done correctly

Who is telling you things & based on what sort of testing ?
Did those people even work on your car to find a problem.

If the Brake Booster was bad the pedal would be hard & no
power assist,not soft.

Do you have rusted brake tubing & fluid leaks ?

I think it is time for a newer car
