Vodafone Idea — Frequent call drop, no range, bad voice quality, no internet bandwidth

Address:

C8, Vishnupuram, Ghulenagar, Vadgaon Budruk, Sinhgad Road

Hi,
Please help me to file a complaint against Vodafone idea. I'm using their services for almost a 11 years, from last couple of years i am facing issue with Frequent call drop, no range, bad voice quality, no internet bandwidth . Most of the time, I cannot do my official calls due to these issues and this caused me inconvenience. I've sent them multiple mails, called their customer care multiple times but it didn't turn out positive. If this was the service then how could they charge us for the monthly usage payment and rent. I want a valid compensation for my work loss and mental harassment due to this worse connectivity.
Please consider my grievance to proceed with this complaint.
