Freecharge Payment Technologies Private Limited - Refund not credited

Let me bring to your notice after lodge complaints in bulk regarding a transaction made by me through Freecharge mediator to the merchant Medlife Pvt Ltd. for medicine purchase. However No satisfactory answer was provided by you to me. Thus this was the intention to send this letter in writing.
On *th August firstly I placed order on Medlife On *th August **** At **:** PM. for purchasing medicines of ₹****.**. Order ID of such order was OR****PSA-***A. Basically My practice is to make such type of order as prepaid. Hence I made payment through Freecharge for ₹****.** to make status of such order as prepaid on *th August **** At **:** AM. For the same Freecharge Transaction Id was smYZqZ**SALKGe-OR****PSA-***A-*-W-*. Subsequently Transaction got failed but same amount was debited from my bank account because i made payment through debit card. Transaction Id of bank for said transaction was S********. In addition to that i expect that free charge will sent said payment to medlife as my amount was debited from bank but while inquiring medlife for the same transaction they claimed that they are not receiving any amount for this order from freecharge. Hence due to this I cancelled order of medlife. So that you are liable to refund my money paid by me.
In addition to above i sent so much mails to your customer care for the refund and also they provided me Refund reference no. However while I informing to the concerned base branch of my bank also file complaint there for non receipt of refund but they also claimed that no transaction are pending for your account as far as they can able to examine my account. Also to the date no such amount is credited in my bank account after waiting for whole one month.
So that ultimate option to the concerned matter was from you that you are required to provide me copy either physical or on electronic mode , of the details of transaction as well as of refund initiated by you as soon as possible.
I also enclosed the copy of transaction and order placed by me to the said letter. So that you can ensure for the same.
I would appreciate early reply from your side. Together with the above if refund shown as not successful after examining the transaction kindly refund the same amount as soon as possible.
Thank you.
