Phathetic service

Wind screen was replaced, and they broke my wiper bolt. I was told to get a qwote taking time off work so they can fix it, wich i did. Once i sended them the qwote they bought the wiper arm and send their own GLASS TECHNICIAN to replace the wiper motor wich in return burned my battery cell as he tested the wipers for two hours and jump started my vehicle. He also brok the clips of my plastic cover covering the wipers. The vehicle since according to their request had to go to VW service centre the vehicle has been standing for 5 days causing us to to take unpaid leave as we dont have a vehicle. 5 days later i am being told that they will only replace the wiper bord. Try phonning they dont answer or transfer and drop the phone.
