Nokia, India — Broken digitizer of lumia 720

Hi Nokia India. I bought Lumia 720 from a local store 4 month back.Yesterday while travelling in the bus due to some rush it jest fell down from my hand and when i picked up i saw it's screen is broken.I heard lot about the gorrila glasses that it not broken easily now while looking in forum it looks like there a lot of people suffered from that problum.Even my best friend was using lumia 520 and even he had the same issue .He repaired it from nokia care and after some days he again had same problem with desplay.He finally bought a new samsung phone.I don;t understand why do you gays make such phones with glass carving out even when lot o[censored]sers are facing such issues.And when i asked nokia care about repairing the told it will charge around 9000 rs ...does that even make sense for a phone of cost 17000rs and you guys are charging 9000 for replacing screen and even i asked them that my display is working fine i only want digitizer screen to be changed and not LCD display to be changed so they told we does not change it individually we replace both LCD display and digitizer screen...at ebay and other shopping site offer it;s digitizer of cost around 3000 just because you guys not change it individually i have to spend 9000...I have read on windows forums that at some places that some guys got it repaired at discount price because there phone was in warranty and some guys called different nokia care centers and they were telling different prices...So i want my phone to be repaired at cheap price if both LCD screen and digitizer needs to be replaced or i want only digitizer to be replaced...Need an urgent response...Please reply asap Details : Phone no.[protected] / [protected] Location : Bhilai, Dist:- Durg, (CHHATTISGARH) IMEI No.[protected]
