Q7 4.2Tdi Brake squeal

[Hyper10]

I was hoping someone might be able to assist, a few months ago I had new pads on our Q7 and when I collected it, the garage told me the discs were worn. I drove around with old discs and new pads for 2 or 3 weeks and no problem, Get new Pagid discs and even after a 1,000 miles, there is a squeal at final braking.
As I'm writing this I just realized that I never saw the box for the pads although the garage tell me they are Pagid.
Is there any brand of pads better or anything I can suggest they do in a friendly way prior to making a complaint.
Any assistance would be appreciated, thanks
