Not satisfied with the service

I bought a car last year March and on the day of collection we noticed that the back bumper was lose and we were told to bring it back after the lockdown has eased, we did that and it was fixed but now I've noticed that the front bumper is doing the same thing and I've been communicating with the salesman that assisted me with purchasing the car but to my surprise when I reported the matter I was told that it could be that the clips have worn out or maybe someone bumped it with the trolley at the mall:-(...

The last communication I had with the salesman was that he'll see what he can do, I mean this was in December on the 23rd and it's a month already and I haven't been contacted...

To say I'm not happy with the service that I'm getting would be an understatement, I am really disappointed and wonder if this is the service that all customers get or I am just been taking for granted...
