Dell India — scammed

Address:

Patna, Bihar, 800017

I bought a laptop from dell exclusive store patna. I wanted to buy something else but i was brainwashed and convinced that the laptop i m buying has all the features i needed. I didn't have any knowledge about laptops. So trusting them i bought that laptop. I had problem from start but i thought maybe it'll get better and i don't live in patna so i couldn't go back to them immediately. After 2 months i took it to service centre and told them about my problem they told me the laptop i bought doesn't have any of the features i mentioned to them. I was scammed. Now what i'm supposed to do with this? I don't think i will ever buy dell laptops
