Reliance Communications — Reliance not unblocking my SMS service

Address:

Hyderabad, Andhra Pradesh, 500001

I am not able to send SMS from my cell to any other cell. I am using Reliance for so many years. Reliance is not unblocking my SMS service on my cell. Firstly, they just blocked it without my notice because of a stupid reason that I am not actively using SMS service. Now, to unblock it, I have called Reliance Customer care 100s of times. They take the complaint, but never acted on it. I am still not able to send SMS to any other number. They just say, there is some technical problem and back end is looking into it. Every time I call, they say, it will definitely be resolved in 10 hours, by 2 pm, 24 hours, midnight, etc. So, but nothing happens.
