Consumer Redressal

I gave my new Micromax A091 phone for repair of broken LCD on 29th July 2014, at their Dunlop Service Centre vide Job No. E030466-0714-11163679. Since then I have been visiting the service centre regularly, every 2-3 days, but they are only replying..\"not done\"...They also asked me to get in direct touch with the company. I have sent them emails also and they keep replying in apology and saying that they are trying to get it done fast. Actually I think they do not have any spare LCD screens, so they are unable to replace my broken screen. I have kept the copies of all the email correspondence with the company. It is now more than a month, and I am suffering without a phone.
