Vodafone India — m not able to send message to 1900

Address:

Rohtak, Haryana

Whenever i tried to send message to 1900. It shows undelivered. I tried about 12-13 times. Now vodafone is not giving option go talk to cc to my number. I dont know what to do. As this is my registered number everywhere. This is not expected from vodafone. Their customer care agent kept telling that your problem will be resolved in next 24 hours but nothing happened
