Reliance Communications — not allowing port

Dear sir/madam,

I am a reliance communications gsm mobile customer in assam from june-2011 onward, as per the mobile number port code provided by the reliance communications to my number i tried to port to other networks like idea, jio and vodafone but reliance communications rejected my porting. And reliance network also not working and i am unable to contact any of their customer care numbers. And they are mentioned the port code is valid till[protected].

As my mobile number is very important to me as i have given this number in my bank and other areas.
