Airtel - Fixed Line Phone — closure of complaint without resolution of problem

Not able to lock phone dynamically. Spoke to their help desk and followed the procedure suggested. Even after that outward calls are not getting locked. Struggled for three days with all this and booked a complaint no 14366784 on 27.11.2008. They assured that their service person will visit and rectify the problem. Did not happen till date and after daily follow up. Was informed that complaint which was booked on 27.11.2008 is closed. Do not know how a complaint can be closed without resolution and inspite of the fact that I have been informing them regularly aboubt non resolution of the problem.
