Poor service and lack of communication

I am so disappointed with Nissan, they must just stop pretending to care about their clients. I logged a complaint last month, still no feedback. Today I spent my money and sent someone to go and check what is really happening with my car, the one that I’m paying every month and yet I am struggling to go to work. Only to be told that they ordered a wrong part so they had to order another one. They have the audacity to tell me that they don’t know when will the part be delivered but they can’t type an email to update me about my car. They so useless and ***********, I am so tired
