Complaint for poor Service

Hi

I bought a new Polo Vivo 2018 at Constantia and they broke the fuse box on the car while they were fitting the tracker on the car at VW Constantia, I have requested that they replace the fuse box on the car. they told me that they ordered part for me and its gonna take a month to be delivered(this day was on 20 November 2018) but i have not got any respond from anyone at constantia. i also have a problem with the front driver window as it makes a nice when opening and closing. i took the car to service but its still doing the same thing. SO AM NOT HAPPY WITH THE SERVICE THEY GAVE ME.
