Tata Docomo — not able to port

Address:	Chennai, Tamil Nadu, 600117
Website:	www.tatadocomo.com/en-in

Tata docomo has barred all the calls and sms in my sim card in chennai circle. I am not able to send the port request sms. I tried all the local addresses of their service centers, all are closed. I haved tried reaching their customer service[protected] thru my airtel number.
The number is always busy and i am not able to reach them.
If i try to send an online complaint request, it says that the mobile number is invalid and i will not be able to send request even.

Please help me generate port sms
