Vodafone India — not allowing me to send port sms

Vodafone doesnt work in my area and they are not resolving the issue. Numerous complaints on email but no reply. When i call, they keep On hold and say it will be done but no response happens. This has been going down since past month.
Once I went to Delhi and network came so I tried sending SMS for porting but it failed. Normal sms went but porting one didn't. They have blocked porting code. Not replying to emails or calls. Zero network since 3 months stil paying full bill but no network.
