Vodafone India — vodafone blocking mnp sms to 1900

Dear sir/mam

I want to port my mobile number but i cannot able to send mnp sms to 1900, as vodafone is blocking this sms. I have complain to them many time, always get the repeated reply that we have raised a complain and it will be resolved within 24 hours. However its been 5 days still i got the delivery failed message every time i try. I have also complained to the vodafone store but still the same reply. Issue is still not resolved. I hope you will look into this matter seriously and get this issue resolved asap. My mobile number is [protected].

Looking forward to get the resolution soon.

Regards
