Asus — Asus zenfone 2 ze551ml complaint

Address:

Chandigarh, Punjab, 160036

I bought asus zenfone 2 551ml on 12.09.2015 and after one month use it suddenly hangs and then totally dead . I went to service centre at sector 22 chandigrh and they told me that its mother board has totally damaged and it will take 5-7 days for repair. First of all company should give me new phone its only one month old but they refused. And now it has more than 15 days passed and my phone has not been repaired. Now my interest in asus zenfone has totally gone and i want my money back which is rs. 15000/-.
Phone serial no is [protected]
i have mailed several complaints but no positive answer received.
I dont want asus phone now i want my money back
