Karbonn mobiles — quattro l50 hd service

I have a complaint about servicing my phone. I have purchased it on[protected] through shopcluse. It has touch complaint specially in bottom three keys (Back, home) and got into service centre at sai telecom on[protected]. Till now my phone is not serviced. I called them and said, need more time. This is not at all a proper way. Three month duration is completed.
Today after continues follow up i went to the local shop from where i purchases he saud that the parcel is received today but the lcd is broken which sounds as if he is playing with emotion.
After the argument they said that they received this broken mobile from tge docket and need more time around two three month.
Please sir take a very strong action so that i can really hold my mobile in my pocket one month i used and after the rest month it is in service centre even came today dated 29/8/2017 and its a broken lcd now advise to taking action
