My name is Hareram A Gupta, I had problem with my Micromax Mobile A350 that the out going voice Mic was not working. I submitted my mobile to Micromax authorised service centre within warranty for repair on 11/07/2015. Till today my handset is not yet repaired. My Job sheet no is W***********. The service centre demanded 20 days, and they have passed till then they have not completed the work. What Kind of service are they providing?? The service centre address is M/S NEW TIRUPATI CELLULARS SHOP NO 2&3 ESTEEM TOWER, MUMBAI PUNE ROAD, KHRALWADI, PIMPRI, PUNE- 411018.
