Micromax — Issue with micromax a111 at customer service center

Address:

560064

I gave my mobile Canvas A111 to repair at Yelahanka Micromax service center on 6th Aug 2015. The only reason I gave my phone for repair is the 3G connection was not working on the phone. They asked me to pick the phone after 4 days, till date the 4 days have almost turned to 4 months. Whenever I call them they say 4 days and the phone is in Delhi. Such a pathetic service ever I have come across. Micromax should look into this issue seriously.Refer to the attached image for the invoice from service center.
