Mercedes forgets the client is a person and selling vehicles with a warranty should mean some security for the client

I from being someone who has loved the Mercedes’ brand and product is left wondering how can customer service be so bad. I bought my car 2 years ago and last year November 2021 the vacuum on the turbo went. I have 30000km driven so another 70000km still to drive under warranty but my car is still in the garage 4 months later , first because no parts were available and now because while working on it they damaged the radiator and that part will not be available for a few months more . You would think they would feel so bad that somebody from Mercedes’ would contact you . No instead you have to phone a call centre where you are told no managers are available . Customer services email you to set up calls at specific times to talk to you then never call and they lend you a vehicle to drive that someone previously has smoked in , you cannot go on holiday in and only you can drive . I have asked on numerous occasions for somebody to contact me as I have bought the GL400 because I like the safety and space the car has yet I can’t have my car because Mercedes has no parts and places no value to the client who has previously owned 10 Mercedes’ before . The only time the branch has called me is to try and sell me a new car where i have to pay in lots of money to be in the situation I was in before the vacuum on the turbo broke which is under warranty . Think before you invest your hard earned money in a business who does not value clients.
