Vodafone India — mobile number portability

Address:

600119

I am trying to port my number to chennai circle from delhi but it seems the company has blocked the messages to 1900, i can send a message to all the numbers but 1900. Even spoke to the customer care center and they have been giving all rubbish answers like restart your phone, don't port just recharge with a different plan. My mobile number is [protected] and i request you to unblock my messages to 1900 and help me generate the mnp number
