Dell India — dell exclusive store, noida sector 18

I had purchased my laptop from a dell exclusive store in april 2017. However, since i had purchased the laptop, i was facing problems due to the devuce not functioning properly. When i had contacted the store, they conveniently blamed it on a windows update for the poor disk performance. However, recently my hard drive crashed. I know what you're wondering, that how does a brand new laptop with absolutely neglible amount of data can have a hard disk failure. Well, the reason is simple, the technician who just repaired my laptop informed me that the dell exclusive store in noida had given me a laptop with a fault hard drive. This only tantamounts to the fact that i have been horribly cheated by the authorised sale support team of dell. I have had a horrible experience so far.. And i hope i dont face any issue henceforth. But i want to make a formal complaint against dell exclusive store in noida sector 18 in atta market for having fraudulently cheated and misled me in purchasing a brand new laptop with so many defects.
