Vodafone India — My new sim card not yet activated after 48 hours

Address:	700047
Website:	www.vodafone.in

I had bought a vodafone 3g/4g sim no.[protected] on 25 may 2017 at rs. 170/-. I also submitted my documents, viz. Photo and aadhar card copy. But even after 48 hours, the tower is being shown on my phone only as "emergency call", but no vodafone sign. I already have made 17 calls to their allotted number : 59095 for tele-verification, but no response whatsoever.
I fail to access a customer care number for this issue.
If they fail to fulfill their role, i would request a refund, so that i can go for some other service provider.
