Bad service and disrespect

I got a bad service from hyundai bedfordview, I took my car for a clutch change last week Wednesday, got it back on Friday afternoon , on drove it but the main issue I had came back, called them on Friday was told I can only bring it on Monday as they have taken cars to work on for the day. Monday I get there explain what the issue is, their technician test the car comes back saying he doesn't feel anything wrong, I tell him but I told u it doesn't happen all the time, he says if there's a problem it might be my style of driving I damaged the car, I asked how it's not even 7days they fixed it n already I damaged it? While I wait for him to retest drive n check for the problem, I called hyundai bryaston n explain the problem, they said I need to bring it to be check but might be a clutch cable, so I go to them and ask did u change the clutch cable the guy at Bedfordview says he could have seen it it can't be the clutch cable, so I asked to be taken home so I get my laptop so I can go to work, they took me, when I come back he says they have adjusted the clutch cable, I asked why didn't they change it he says coz it plus minus 50% okay. I left but now my hand brake is so hard, I have pains on my arm from using strength to pull it n I really don't want to go back to them as they will mk me feel like am stupid like they did. I wish to take it to bryaston as I usually dealt with them till I moved this side but I don't think it's fair as they didn't do the warranty claim or the job. Now it's a waste of my time and petrol having to go to them. I work on the road I don't have time nor can afford not to have my car as am in sales seeing clients they already wasted 3 days were u sat n could not work.
