Reliance Communications — rcom (ex mts) not able to reach call center, no response to e-mail. cant pay bill

I was mts data card user almost since 3 years, since few months internet is not working and came to know mts is closed and merged with rcom. After merger, am not able to pay bill online and local dealers not accepting payment. Rcom promptly sent bill for december month including late fee.
Again i trying to pay bill through rcom online payment but it is not accepting mts number, dealer still not accepting payment.
Paid through paytm, but still there is no acknowledgement from rcom regarding the payment.
I want to discontinue this data service by finalizing outstanding amount, but no response to email and call center not working.
This seems open loot of innocent customers, paying money for nothing
