Bad customer service

I am battling for 2 months now with a problem on my Renult Sandero its not even a year old. Parts are ordered from France and there is no feedback on the process. I try and phone but the person never answers his phone. When I do get hold of the person he gives me empty promises. I am still waiting for feedback from them surely even in our pandemic they can give me some feedback especially after 2 months. its such a pity Renult is such a nice car......
