I took my car in to have my clutch installed with aftermarket parts, in which they did so. The clutch kept having issues with pressure and they recommended I change the master and slave cylinder, which were also done with aftermarket parts. After installing these parts, I still had issues with the clutch pedal maintaining its pressure. The entire system also had a strange rattle during neutral that sounded like as if there were rocks rotating around and around. I dealt with this for over a year and a half afterwards off of the assumption that it was just "how it is" as they could not fix the issue.
Fast forward to recently. I took my car to another mechanic in which they quickly recognized the problem. All the aftermarket parts that were installed in my car were not only done improperly, but were not suited for my clutch as it involved removing a number of hoses that were important. I had to repurchase a stock slave and master cylinder, along with an entire new transmission due to the possibility that the install destroyed the transmission. This entire fix cost me $3000. My clutch and transmission now maintains pressure, has no rattling noise, and shifts smooth.
What upsets me the most in all this was not only the waste in time, but essentially that they never came to me to admit they didn't know what they were doing. On top of this, they never gave me the old parts they took out, in which my new mechanic informed me, could possibly have been reused and saved me some money. At what point in the install did it ever occur to them that perhaps they should give the customer options behind what they are asking them to do because essentially what was asked they either could not do, or did not understand?
