Unni, relax, nothing is going to improve because of your complaint. I sent a similar complaint about a mis behaving taxi driver 3 years ago, called  all the customer service, faxed the complaint to PRO, called other senior officers, yet no one responded to me for long time, the more the responsible persons in office maintain their silence, the drivers will continue to do their atrocities with public. this is not first or second to read, umpteen such complaints were seen, no results.
