Brake Pads: Replace When Changing Rotors?

Hello,
There's something to complain about with my A6 AKN again.

After only 20,000 kilometers, the brake discs are completely worn out.
Although my friendly mechanic wanted to completely rebuild them when buying.

If they are on now, he probably 'forgot' and only replaced the pads.

How should I act around him now?
I want to start everything from scratch again.
Is this a good idea, or can I still use the brake pads that are still in good condition?
Should I break in the new tires again?
Or am I damaging the new windshields with this?

get new tires.

No, that's not good.

Sure, the pads will wear down and conform to the shape of the discs.

Conclusion: Get new tires...

Thank you both.
I have an appointment next Tuesday for the 6th repair/warranty work.

I will insist on new flooring; I'll let you know how it turns out.

Okay,
I saw him again today.

BUT:
They only replaced the windshields at the front.
left the back and all the toppings .

although it was agreed upon otherwise.
Are they trying to fool me?

I temporarily took the car because I didn't have time to deal with it properly.
and I'll figure something out by Friday.
This will be the 6th written complaint filed since November 2003.

or should I go to another friendly car dealership?
and send the bill to the incompetent person.
What procedure would you recommend to me ?
