Telecom Regulatory Authority of India has relaxed the time for operators for resolution of billing and charging complaints by consumers. From the earlier four weeks, the regulator has relaxed the time to six weeks for resolution of all the complaints. The regulator said, service providers emphasised that there might be some stray cases, where due to unforeseen reasons, there might be delay in resolution of complaints beyond four weeks, and hence the benchmark of 100 per cent could not be achieved in some instances.TRAI has also revised the response time for answering customers calls. The regulator said, 95 per cent or more calls from customers should be answered within 90 seconds. The earlier benchmark was 90 per cent calls within 60 seconds.
