Joister — calls even after terminating internet service

Address:

Pune, Maharashtra, 411014

I have been getting continuous calls from joister even after telling them thousand times (Over calls and through email) that i don't want to renew their internet connection. It is irritating to receive these calls.

I have been sending them emails from 5-sep-19 and still they have not stopped calling me. Its like a harassment. Please don't call me
