Airtel — international roaming not working in australia

I did two recharges (INR 296 and INR 1499) to activate my international roaming for Australia on the date 21 March 2019 and today is 23rd and it is still not working.
I called customer care and they asked me to do restart and did all the troubleshooting on 23rd march but all was in vain and when i asked for my refund or add value if they are not able to refund they declined.

I am raising this complain so that I can get justice and get my money back.
