New car disappointment

<p>I bought new Renault kwid on 23/11/2016 on 29/12/2016 it failed to change gears especially gear 4, I took it to Renault dealer on the 30/12/2016 and they said they'll fix it :-[ up to today my car is still at Renault service centre. I lost hope and even think of changing it soon (first cut is the deepest) I thought I will own it for a long time because it is my first car</p>
