I am still waiting for feedback

I just got a new first car and was financed by MFC from right cars, i have complained to right cars about missing engine cover, front light thats not working and wheel alignment which i was told by Shaun from the dealership that i am booked at their workshop for all those to be attended to. on the day, i went to the workshop and met with manager Ken who said he will not be doing any work on the car. i wrote a formal complaint to MFC to intervene 2weeks ago to which i received no response to date. i then called MFC again on the 01st of October 2018 which i was told that Shaun will call back before end on business day and today is the 4th and i am still waiting
