Reliance Communications — Number disconnected without any information

Dear Sir,
My name is Varun Prashar and i am from Patiala, Punjab. Few years back i got a new number from Reliance Mobile which was [protected] with lifetime validity. I distributed this number throughout my whole network of property dealing. But a couple of days back Reliance disconnected my number without any intimation to me. Now i am so disturbed, because of this my work suffers a lot. Please do suggest me what can i do in this condition. I am helpless.
