I am residing in the town of Biswanath Charali, Assam. Three months ago, the network worked well although there was network unavailability for some mins in the day, it wasn't as frequent as it is on this day. Also the network changes from 4g to 2g very frequently which makes it impossible to browse the internet for some important work. The problem is not with my phone but everyone having a Vodafone sim here is facing this problem. Look into this matter and fix it as soon as possible. It's been 4 weeks that the network is so poor.
