"In fact, even complaint escalation has been on the lower side for many months now. We get very few investor complaints routed through SEBI these days," Ramesh said, quotes ET.

Market regulator SEBI, in the early 2011, took note of rising investor complaints in mutual funds. As per the last year complaints records, investors mostly faced the trouble non-payments of dividend and redemption proceeds. And for the worst, there were also several fund houses that had complaints pending mail of 3 months backs left unread.

Twenty months down, most fund houses have made several efforts to reduce the turnaround time (TAT) in addressing investor complaints. Only ICICI Pru MF, SBI Mutual, Birla Sunlife Mutual and Tata MF recorded an increase in complaints in 2011-12. These fund houses managed to rectify most complaints in less than 30 days, said top mutual fund officials.

The industry has done well on all fronts except in communicating unit account statements, where the number of investor complaints has risen in the past one year. According to industry sources, fund houses have been pelted with complaints relating to errors in fact in account statements.
