Dell India — Laptop Replacement for dell inspiron

Its been almost 3 months since i bought the laptop and i haven't been able to use it properly even once.

I had requested for the replacement and the laptop was collected more than 3 weeks ago but now i have no way of tracking my order.

When i called dell they told me that the only way to contact the replacement unit is through email or to wait until they called me.

It would have been fine if they at least responded! But they only reply when its convinient to them and i dont think they even read the issues i mention in email.
I have explained over a hundred times that i wont be in the same country after jan 14.

I am so tired and frustrated right now. It is ridiculous how they can't handle a simple replacement order.
