I would like to let you know that my * yr old daughter had dropped my old phone and it lost its display.Life without smartphone is impossible these days so on the same night i order a phone from TATACLIQ from my hard earned money.If you want i can provide the image of my old sony phone which has lost its display. I received the phone on saturday , put the sim on sunday and tried to make it functional .As soon as i tried to use it a pop up notification started showing up for volume control which was automatically silent.I tried hard , went through online search to understand the problem and found that its inbuilt malfunction in the phone itself .There when i tried to switch even power button i was not able. that i am waiting for a return instead your team is asking and reasking IMEI number,photo of box etc.which is very strange and can verified by a simple call where i can read it to them if they can't read. I have attached image of IMEI number with this email as well.
from last few days during my office hour i am continuosly spending hrs to handle my own return request queries,photographs sharing etc if a defective phone is delivered to me then i failed to understand is it my problem or tata cliqs? is it in connivance with the online fraudsters and scamsters which i have heard and read..

I find violation of my basic consumer rights and sales purchase agreement where i mean i gave **K rupees to tatacliq and i am supposed to receive a fully functional brand new phone .They took the money and handed me a defunct mobile phone which was highly unexpected for me as TATA commands respect in India in service sectors.
