VW polo front batch with pratley putty.

we bought a used VW POLO and we asked question and checked the car , at first inspection car looked ok, but after two weeks Front VW batch started to come out and took the car back on inspection the batch was attached with a pratley putty which it was never disclosed when we bought the car , i asked them to replace or fix. the manager used double sided tape which is not seating nice you can see gap. went back he promised to replace the front grill. today he tells me he doesn't see anything wrong with the car he will never replace the front grill and i have waited two month without any communication from him.
