Mercedes-Benz International review: mercedes damaged my vehicle when I took it to them for a service,

When you take your car in for its first 9000km A service to a Mercedes Approved garage in perfect condition inside & out, you do not expect to collect your car with a greasy interior, dirty carpets & damage to the body work.Normally in the past Patrick Launay in Angouleme 16430 would do the required work & return the car in an acceptable clean condition, NOT NOW! total denial from them about the scrape on the body work, they say the car came in for a service not a valet, we now wonder if the oil & filter was changed and did the damage occur from one of the thugs working in the back room taking the car for a spin round the block.We also complained to Mercedes their reply we have no proof that the garage did the damage as it took 3 hours for you to return the car, we live over 1 hour from the garage & it was not until our son washed the car the damage came to light & a lunch break was included in the 3 hour return period.What a disgusting service not only from Patrick Launay or is it Loony but also from Mercedes France.I know now that customer service does not exist in France.
