Bad customer service ever!!!!!!

I bought a car (Audi A3 2018 sportback) at Williams hunt the glen in June and went to fetch it towards the end of June, and when I got it, it was already due for service and the salesperson said I must bring it in after 21 days, which I did and with no issue. Then when I took it to them they said they don’t service Audis there but they will take it to VW, and guess what, they didn’t instead they serviced it in their own shop. After, that service, guys my car came back with issues, the thermostat housing is leaking, the left back wheel has an irritating sound that I do not know and understand . I haven’t reached 3 months with that car and what hurts the most is the amount of money I pay every month, which is a lot for a car that has such problems and when I sent them emails they do not come up with solutions instead they are ignoring my emails.
