Flipkart — no resolution for problems with redmi 1s

I have purchased one redmi 1s from flipkart via order no. OD[protected] dated 25.11.2014 and delivered to me on 3.12.2014. i started using this phone from 6.12.2014. for first 2-3 days the phone was quite good. problem started from 10.12.2014 when in morning all of a sudden battery drained to zero from 88%. it was morning and i waked up and picked up the phone to switch off the alarm means i was not using the phone and battery become zero. it happened for atleast 4-5 times from 10.12.2014 to 13.12.2014 out of which for twice vattery become zero and for rest of the time the phone get switched off after becoming inresponsive. I had given a complaint regarding this on 12.12.2014 and i was told that technical support rep will contact up to 4.30pm and next day i received an sms due to hheavy work load they were not able to contact me and i will be contacted up to 1.30pm of 13.12.2014 and third time i received the same thing that now i will be contacted on 14.12.2014. yet i have not received any technical support and yet i am not aware what resolution will be given to me. so i appeal to all pls do not buy redmi 1s or note from flipkart. flipkart is importing this phone in india and have no technical expertise to solve your problems. they will keep riding over you and will not respond. i suffered a lot as i have this as the only handset to use. do not get driven towards this cheap phone by alluring feedbacks on different sites as i know atleast 5-6 people having same phone and facing problems and flipkart is not responding. they are making people fool by organising sales and showing these phones out of stock... now i have decided that i will file a writ against flipkart and see how they shed their hand from their responsibilities.
