Pathetic after-sales service

Its me again. And I'm still waiting for my phone. You people are too slack. Its 3 weeks now and there's been no repair conducted on my phone. I now demand a new phone. Reasons are - my phone is still under warranty, your repair guys told me it will be repaired in 3 to 5 days (its been 3 weeks now), I have no social life and no communication methods at all (no email, sms or calls), I have to borrow a phone from a friend, and should something happen to me or my family while my phone is with your repair guys, I will make sure hold you responsible and you will incur the costs because I do not have anybody's contact details. I borrowed a phone so you can call me on *** between 4pm and 7pm on Tuesdays - Fridays and anytime on weekends. I Still want a new phone. I refuse to wait any longer. I will wait for your call.
