Airtel — sms service not activated even after 48 hrs.

I had swapped my old sim with a 4g sim on 25/09/2017, and i was told that the sms and data services will be started after 48hrs., but i am still not able to send and receive sms. I called customer care but they could not help me as date of activation of my new sim has not been updated, they told me to wait for 72hrs. More.
