Nissan Motors — i am complaining about my nissan sunny up16ay 9846

I lost my car key on 5 june 2020 and then i contacted mr gaurav ([protected])
From neo nissan sector 63 noida. And he told me that he has ordered a new key for my car same day after i provided him my car details with insaurance paper, registration copy and police complaint same day. But after contatcting regularily i still have not received my car and he does not even pick my phone. And then i contacted gm of same branch contact no[protected] and he also doesnt give any satisfactory answer. And yesterday he called me to his office and said i will provide you another car for the time being and when i reached there car was not ready and i had to come back 40 kms by cab again. And today none of the member there picking my phone. How irrisponsible team. Please provide me the solution asap.
