Airtel — Recharge was successful but no benefits received

Dear madam/sir,
I got a recharge of rs 45/- on my Airtel mobile number [protected] with 28 days validity from freecharge.in website, but it still says insufficient balance.

I urge you to kindly look into it.

This is what freecharge.in customer care said,

"The operator has confirmed that the transaction was successful with following detail -
Order ID: FCVM[protected]
Recharge Number: [protected]
Recharge amount and date: Rs.45.0 and 08-Jun-2020
Operator ID:[protected]
Plan details: ₹45
Enjoy Local & STD calls 2.5p/sec, National Video Calls 5p/sec, DATA 50p/MB; SMS Re.1 Local, Rs.1.5 STD, Rs.5 ISD
Validity: 28 Days"

I got a success SMS on my mobile too from Erecharge (attached Screenshot)

Thank you.
