TRAI got maximum complaints against airtel, followed by Reliance and Vodafone
The following table lists the number of complaints that TRAI had received against telephone operators (issues related to billing, tariff, metering, activation of chargeable VAS without informing the customer etc) over the past three years and the complaints are only rising. Do note that these are the complaints that TRAI had received, not the complaints put up to respective operators:
TRAI has already forwarded these complaints to the operators to have them resolved ASAP. TRAI has also notified the operators to follow Telecom Consumers Protection and redressal of Grievances Regulations, 2007 (detail on the same can be found at http://www.trai.gov.in/trai/upload/Regulations/64/regulation4may07.pdf). This notification explains the procedures that telecom operators need to follow to handle customer grievances and to make the grievance redressal system effective.
