Reliance Communications — My barcode is hacked

Address:

New Delhi, Delhi, 110094

I got a barcode on my phone but when i did go to the store to avail the sim i found that it has already been redeemed by someone.. The jio office people said nothing can be done about it. Like what the hell? Its my phone my bar code and someone else is using the sim on my barcode. Please look after this matter and make me issue a new barcode so that i can use jio services on my phone.
