Dell India — Alienware headset replacement, struggling more than 1 month

I was very big fan off Dell products (Earlier), So I usually buy dell products. I purchased a Dell laptop recently and they provided a Dell Alienware headset as goodie with additional amount of Rs. 499. I received the headset and it was not working properly. I contacted the support team and they analyzed and confirmed that it is manufacturing defect then they assured me that they will arrange for replacement. I am following up them more than one month but they are always saying please wait for 5-7 days. I crossed multiple 5-7 days for this replacement. Now a days Dell is not providing proper customer support and products quality is also not up to the mark. I don't like Dell now a days. My Complaint details given below.
