Hi,
I, dr salauddin haque would like to put a complaint regarding my RC book delivery.I purchased a creta car from mukesh hyundai, Baguihati branch which I got delivered on 18/10/2020. But till date I have not received my RC book from them. I have given several times of reminders but the salesperson mr sumon and other officials from mukesh hyundai including CRM Ashmita but nobody is taking care this and harassing me since last three months.
