Bad Aftersale service

I had my windscreen replaced by the PG Glass mobile team. Good service.

I noticed that there is a whistle sound when driving on the highway which I reported to PG Glass 4 times by phone and advised them that there is a fault with the installation. Ive been told 4 different times that the mobile team manager has been notified of my complaint and will phone me. i have received no feedback from anyone around my complaint

Please can my windscreen be redone as the noise is unbareble
