Unsatisfied customer

I've claimed my windscreen in July only to be cracked again in few days then in September again I claimed for the windscreen and paid access and they sent the very same people and when I inspected the windscreen I found that it is a **** windscreen that's why it cracks even when you are washing the car, I told the people who were supposed to replace the windscreen that I want an original windscreen not the **** one because I will keep on claiming for windscreens as they just crack, I was told that they will escalate the matter to the insurance company and I've waited for 2 weeks and no one is coming back to me. I decided to give them a call to ask what's the delay since I've payed access same day they requested it, the consult told me that they don't, who is supposed to know? I pay my premiums every month and yet when I am supposed to get service I get ****y service, I am very angry that I have to drive a car with a cracked windscreen while I am paying monthly insurance premiums. No one knows exactly what is the way forward and I am busy wasting my airtime calling the insurance company while being transferred from pillar to post. What will happen next if I am involved in an accident? I am going to be given the run arounds but when is monthend money is debited in my account.

I want answers as in yesterday.
