service book not put back

i did a service a vw northcliff and after the service my service book was not but back in the car i have contacted them and they have replaced me with a service book for another vehicle as first i thought it would not be a problem but since my car in generally new i went to a dealer and without the correct service book my car would lose value when resold. and i was made to pick up the service book from the branch i live an hour away and i was told i would have to drive at my own expense to get the stamps at other branches. all my services were done at VW agents for the reason that they would be professional but i was wrong. that was my second service. my third service was done by VW centurion the commercial side the service was done and that everything was fine besides my tires which i addressed. 3 months later 1500km before my fourth service i had to go in because my brakes were fiinished and had also eaten away on my brake disks. i am not a person that knows much about cars and i feel taking it to an agent they check all these things and i should have been warned that i would need to replace the brake pads. now i must also replace my disks aswell pathetic service from all of them
