Reliance Communications — mts and rcom merger issue

Address:

Bangalore, Karnataka, 560037

I am using a mts data card, now i want to surrender my postpaid data card. I don't want to use it anymore. But mts customer care is down, rcom 30333333 customer care number also not working. But rcom is sending bill for the same though i am not using it. I have visited rcom shop also, but they told they are not handling mts. Send email also to rcom customer care email address but no response. Please close my mts data card connection [protected]. I don't want to pay bill anymore.
