Jio — jio broadband services

I had my jio broadband payment registered for auto debit from the credit card for monthly bill payment.
The bill due was 28th april 2018.

I sent a mail to the jio asking when the auto debit will be done.

Jio replied there is no auto debit instruction on your account

Fearing late payment charges i paid 589 rs due on[protected], and jio deducted another 589 rs on[protected].

Based on jio reply i paid my outstanding, also jio debited on auto debit

How to get the refund of 589 rs
