Vodafone — Problem in Generating UPC Code

Address:

Srinagar GPO

Dear Sir,
i am not satisfy with VI Network due to several reasons...Hence, i thought to move to Airtel...then i have started
to send SMS to 1900 for Porting...
but, iam not able to send only for 1900... as far as other numbers are concerned there's no problem as such I'm able to send sms to everyone but not to 1900 and it has transpired that 1900 has been blocked deliberately and the errors shown is "message Could not sent" is showing...tried 10 time...
by speking to Customer care for solution...they keep giving non sense / irrilavent solutions: -

1. I recharged with monthly pack of 149 plus main balance as well
2. i suppose to change message centre no.- did the same but no result...
3. i have to change the handset - tried but no result.
4. Raised an issue to the appellate authority as well

Please help me out for resolving the issue .
