Vodafone India — vodafone india not being able to send porting sms to 1900

Address:

Pune, Maharashtra, 411048

I am not satisfied with Vodafone Network. Hence, i want to move to Airtel but sending SMS to 1900 for Porting is showing failure for multiple times.

While I tried to reach out ot Customer care more than 4 times and all time getting different answers with no quick resolution.

I was asked to:
1. Mobile recharge
2. Change message centre no.
3. Take out Sim and reinsert and then restart the phone
4. Go to the nearest Store for help.

It has been 15 days now and hence Require an earliest resolution.
