Vodafone India — unable to send port message

Address:

Panipat, Haryana, 132103

Dear sir,
I am having network issues for the past few months, so i have decided to switch to airtel, but i'm unable to send port message to 1900, every time i try to send message, it's showing not delivered. Even the customer care executive are giving absurd and non-sensible replies, further they are not answering any call from my number. I had earlier also mailed the same problem twice but of no use as i'm getting non-satisfactory replies.
..
Please help me...
