Consumer Redressal

I had purchase gionee elife S7 handset on 2nd of may but only in 14 days its camera stops working.As per customer care req i gone to service centre and submitted my handset (NEW AGE COMPUTERS RAIPUR C.G)on 16.05.15.They committed me that i will get back my phone in 7-10 days but i was unable to get my handset back....when i call them they dont give any update. But after one month exactly on 16.06.15 i gone to service centre i saw my handset there but again checked camera its flash was not working. I got irritated becoz i have purchased a 25000Rs handset and unable to use it for 25 days. The Lady there was very rude and said to re-submit the handset....I have jobcart written proof that i came to recieve my handset and problem not resolved..Also i have sent a mail to them to pls replace my phone if you are not able to repair it fix .Now i want my handset to be replaced or want my money back within 2-3 days. I am very very upset with the service GIONEE COMPANY is providing..
