Aircel — port message request not confirmed

My name is shibaji banik. My aircel no. Is [protected]. Last few days aircel network give me so much trouble i. E calling problem, no tower problem etc. That's why i decide to port my mobile no. To other network. 2 times i send a sms (Port [protected]) to 1900 from my mobile for porting purpose, not yet i didn't get any response from aircel. I also call customer care 3 times, but every time they tell me they have some technical problems. Please solve this problem as early as possible.

Regards,
