Tata Docomo — unable to generate upc code

I am unable to generate the port code for my tata docomo number +91 [[protected]], due to which i am unable to port my number to other operator.

Everytime i send the sms (Port [[protected]]) to 1900, instead of port code, i get the following message.

"send any of the foll: new short codes:sms cri to 58243 for cricket, sms bid to 57272 for bid n win, sms tune to 57886 to get ringtone. Rs3/sms"

I have tried sending the sms for many times and got the same reply instead of the port code.

It seems tata docomo is trying to deliberately block the port code generation to restricting me to port to different service provider.

Please take some action against these guys.

Thanks,
Gaurav
