If you told them directly to change the radiator and they didn't, yeah, that's not right.
The plan is in a couple of weeks when the Service G is supposed to happen, the computer says in the display, that when I go for this service interval, I will say „I am no longer asking, but demanding you replace the radiator and flush the cooling system.“
I take time, I rent a car so there’s no stress about getting to work on time, I even wrote a letter and checked with a translator (not Google by the way). Surely, that should be enough.
I had also said „I bought this car in November, I don’t know the age of the radiator hoses and please change those as I don’t want to be on vacation somewhere and have a problem.“ when I got back, the mechanic said „since charging the system and no leaks came up, we don‘t just change hoses for no reason.“
I had then said „I am aware of the Klack Klack Klack noise on start up when the engine is cold, if it’s a simple check valve, please fix it.“ nothing was done or explained to either.
I am annoyed because I don‘t want to get salty and think „ah, I only know best, if you want something done, You do it yourself“ type mentality, but it’s damn hard not to.
