Idea Cellular — issue in call both incoming and outgoing call

Address:

Chennai, Tamil Nadu, 600062

I'm ganesh, i'm not getting call (Caller get i'm out of network coverage) and i'm unable to make calls. Howeve, my interest service is working fine. I raised the complaint but its for no issue. I'm experiencing this nearly two months. I'm using whatapps calls for my communication. This is happening in certain areas only. The idea showroom executive advices me to change the sim (It doesn't make sense to me perhaps other location are working fine), and they say it may work. If its till not working i can change the network service provider.
