Airtel — unable to make 4g calls

Address:

560093

I am unable to make outgoing roaming calls from my phone number.
I recharged for 399 through the airtel payments app, my phone is lenovo vibe x3 which is a 4g lte compatible phone. I was using jio previously and i think i made a huge mistake by recharging the airtel sim which i had. I am unable to make any calls. I am however able to use the data pack and it shows 4g but the speed is too less to be called even a 3g.
I am currently residing in kerala and although the recharge pack that i did said roaming free, std and all local calls free and and 1 gb per day for the next 70 days, the promises have not been met.

Please take the necessary steps to resolve the issue at the earliest.

Faithfully,
