Panasonic — My smart phone not returned even after 2 months... No proper answer given by customer care

Address:

New Delhi, Delhi, 121006

I have submitted my panasonic eluga L 4g smart phone at panasonic service center for repair on 5th march 2016...and till now they say that my phone is under process ...they are missguiding me by saying on every call since 24th march 2016 that your phone will be given back in 6-7 days ...but after the period is over they just extend it to more 6 days ...i am fed up with it and now planning to complain in consumer forum...
