MADURAI: During summer days, many passengers, who travel on the much preferred air-conditioned buses, have been experiencing hardship as most of the air-conditioners are not working properly, A Sankar, honorary secretary, Empower India, Centre for Consumer Education, Research and Advocacy, Thoothukudi said on Wednesday.

Thankfully, the government toll free numbers-‘18005991500’ for grievances or complaints acknowledge by sending messages to cell phones of those who called on deficiency in service. But such serious concerns about the non-functioning of air conditioners should be addressed at the earliest to ensure better passenger service in buses.
