Dell India — Dell laptop [protected]-cd slot giving problem

I have purchased the above laptop from vijay sales, infiniti mall andheri on 14/06/2016. Yesterday ie 26/06/16 when i put the cd for my work the laptop started giving a peculiar sound and neither was the matter copied to the cd. I phoned vijay sales immediately and they told me not to come to their store as they have alot of customers and are not in a position to attend to me. They asked me to come today. When i went today they told me that i would have to go the dell service centre in andheri as they are unable to rectify. I was asked to phone the dell service toll free no. There i was told that i would have to br ing the laptop to the service centre. I took the laptop and was informed that they would replace the cd slot and it would take 4 to 5 days. My grievance is that why as a consumer i should suffer for a defect in your product. What is the quality check youare having. I was made to run from pillar to post. Why have the toll free nos if your engineers cannot come and check. I want the laptop to be replaced since it is manufacturing defect. Are you trying to fool the customers. I am very much aggrieved. I purchased a dell laptop thinking that i was buying a good laptop. I am very disappointed. I must state here that lenovo and acer which are cheaper are much better and give much better service. I have always used the cheaper laptops and this time i thought i would upgrade but did not realise that i was asking for trouble.
