Campbell & Cameron Volkswagen Charged me 4K on motor repair 3 months later motor breaks again saying not there fault after telling me it’s guaranteed for 2 years Lasalle Quebec

Where do I even begin... started back in feb 2020 my engine broke due to a faulty timing chain that was in the middle of a class action suit... took my Volkswagen CC 2011 to the dealership CAMPBELL & CAMERON VOLKSWAGEN LASALLE QUEBEC DEALERSHIP... I told them I could not afford to fix the repairs and that I was waiting on the class action law suit decision and they said ok and were understanding...

fast forward to end of May 2020 was told the class action settlement was reached and was told by the administration of the lawsuit to go ahead and get the repairs done, after months of being told by the class action administrator that my car was covered and listed in the lawsuit they turn around at the last minute and tell me only 25% is covered however dealer already did the repairs totaling approximately 6K I had to take out a loan for the 75% out of pocket, dealer did the work told me work they did was guaranteed for 2 years... fast forward on 3 months...

motor breaks again the dealer confused told me I have pieces of metal in the engine and that they think it's from the crank shaft that is in the lower part of the motor which they are saying they did not do work on... I don't know what to do I know I'm being ripped off... they told me that I would need to go to a scrapyard buy a motor (out of pocket of course) and they said they would install it for approximately 3K SO ANOTHER 6K OUT OF POCKET....

they said at the end that I owe them 250.00 for the time they worked on the motor (that they guaranteed) I HAVE NEVER FELT MORE RIPPED OFF IN MY LIFE THAN WHAT IVE FEEL RIGHT NOW FROM VOLKSWAGEN CAMPBELL & CAMERON VOLKSWAGEN ALSO I CALLED VOLKSWAGEN CANADA WHO SAID SORRY NOTHING WE CAN DO.   UNBELIEVABLE SITUATION FROM A CAR COMPANY I ONCE LOVED
