Jio — unable to send message from jio to all numbers

My jio number is [protected].
I am unable to send message from my Jio number to each and every number since last two months. I have registered complain 7 times in the last two months but they are not resolving it.Actually, they are befooling me.
I want that they must resolve it otherwise they must pay my amount to me.
That's it.
Thanks.
