Mercedes not living to the value which says best or nothing

I bought a brand new C220 Mercedes benz 2016 model and now it has been showing an engine light and have been taking it in and out many times. Rosebank mercedes have not resolved the issue. I am greatly disappointed with the C220 product and from a lay mans perspective i think it has a manufacturing fault.

Called Rosebank mercedes yesterday and they did not even bother to call back how sad.

I am a Mercedes customer as i also have a C180 but now they are not living to the value which says the best or nothing. I feel i should dump the car in the country side and leave it there as it is proving to be a cost to me and no one is assisting me

Maybe Mercedes Germany can assist

Frustrated customer and i would advice other customers to think twice when buying cars
