This phone got dropped at a railway station and got the screen cracked. After searching motorole service provider in dombivli i found one media enterprises and found this to be mobile shop step in mobiles in dombivli west. The person there assured me display replacement in two hrs time charging only rs2300. I gave the mobile in working condition on 2nd july 2017 and got it back after they tried and spoilt everything on 3rd july. I was advised by the shop keeper to go to thane motorola service center and was assured that it will not cost me more than rs2300. On 4th i went to motorola gallery and found that the mobile was completely damaged by the step in mobile shop. I had given one intex mobile also alongwith motorola for charging port replacement but they damaged the camera and earpiece of that mobile for which i had to spend rs 1004 for camera at intex gallery. Now step in mobile shop has taken back the motorola mobile from 04th july 2017 but not responding. Please help
