20 Years Old Carrier Central Ac Units

My carrier central air conditioning condenser fan and compressor is not kicking on. Some shady local technicians said that it was a problem with a capacitor. They also said they replaced it with a new capacitor.
When i looked in the service box a portable "test" type capacitor fell out and was dangling by the leads the "new" capacitor was not new but WAS different than the one which was previously mounted in the box.
The magnetic contact which i showed them to be burned and malfunctioning was even more burned and pretty much welded in the on position. This switch was what i thought was the problem to begin with. They charged me 200 dollars and were there about 20 minutes .
I had to throw the main breaker because the outside unit would not cycle off due to the melted magnetic switch . These guys repeatedly told me to SAVE my money because the aging yet previously reliable compressor could suffer catastrophic failure at any moment.
Do you think leaving both those capacitors installed and failing to change out the magnetic contact switch was negligence, incompetence or an act of sheer sabotage.
I am very upset with these people no matter what he answer to that question may be. It was 100 degrees yesterday and expected to be even warmer today. The permanent capacitor is an amper N144050R350 and looks to be either 35 amps or 75 amps it is to beat up to read. The model number is carrier 77CA04300. serial number is 0388E14139.
I have some knowledge of the industrial refrigeration field, but am no expert. Any info or advice will be appreciated.
