I got an issue of power supply issue which is resolved but they have destroyed my device microphone. Due to which i can't use that device anymore for only calling purpose and all the other functionalities of that device is working fine. The device is unusable due to that issue only. The name of micromax service centre is lk smart care, pimpri where they have told me that the microphone chip of that mobile is not available in market. So, please register a complaint against this issue and help me by resolving this issue as soon as possible. Still, didn't get any response.
