Sony India — Worst experience with sony xperia m4 aqua

I am experiencing a lot of problems with my sony xperia model purchased on october with 2015. The mic is not working at all and touch screen is has been a headache. When i contacted support center, they are telling to keep the phone for 2 weeks. Being an working person and having no backup device, i am not able to manage the same. Also it is extremely heating up which is causing a lot of problem.
Hence i require a quick resolution to the problem. Since the phone is in warranty period i need appropriate solution or else i will be enforced to go to consumer forum.
