Bad customer service .Refuse to take resposibilty

Early this I took my ford focus to ford bruma for clutch recall , it had no CRACK on windscreen . When I collected the vehicle around 18H00 ,I did not notice the crack because it was dark. I only noticed when I get on the road that there is something wrong ( the wind screen was cracked on the driver’s side). They damaged the windscreen and refuse to take the responsibility. Mahadi Masopha showed me the pictures they took when I brought in the vehicle but there is on windscreen picture(maybe it was deleted).
