Asus — Very poor repair service of zenfone 2

Website: asus

I have purchased an asus zenfone 2 from flip-kart. in may 2015. after few month its rear speaker stop working from 12 sept 2015. On 14 September 2015 i have given my handset to jamsedhpur service center for repairing. but according to them they are unable to service the product because asus is unable to provide the spare parts in time. asus is ignoring in providing the parts in time. As i am working man and my work completely depend on my phone for my work. it is already 10 days, and due to this negligence i may lose my work. I called toll free no- they told me that the spare parts for asus zenfone is not available in India, it will come from tiawan. and they provide me maximum time frame of 7 oct 2015. but till date they are making excuses of parts unavailability. if you are unable to to repair the product then please replace my handset or provide me the refund. thank you.
