Vodafone — Sim inactivation

I had requested for porting my mobile connection from vi to other network as I was getting very poor network connectivity on vi. I got call from their retention department mentioning that if I update sim then network connectivity will improve.
I visited vi store and got my sim updated but it's not activated. I tried contacting customers care of vi through whatsapp, chat, app, email and twitter but i didn't get any response. There is no customer care number to be contacted from other mobile network and i don't have other vi sim to contact on 199.
I am struggling because all my transactions are stuck as I don't have active mobile connection which is resulting in receipt of OTP.
Such poor and irresponsible service from vodafone idea was not expected
