Vodafone India — unable to send port message and now unable to connect to vodafone executive

I am unable to send port message to 1900 from my vodafone mumbai prepaid number, while i am able to send message to any other number!!!
After fillowing all instructions from vidafone executive i am still unable to port. My service request is also not resolved yet. Kindly do not harrass customers like this by intentionally blocking port messages request.
If this will not resilve by today or max by tomorrow i will go to higher authorities for help.
I have other vodafone postpaid and i will stop uaing that as well if this issue doesnt resolve asap
