Reliance Fresh — refund for double payment

Address:

F/24, Sai Vihar Residency, Sai Chowk, Sus Pashan Road, Pune, Maharashtra, 411021

Dear Sir,
I had done a shopping of Rs. 705.33 on 5/06/19. I meant to pay by using Google pay (transaction ID[protected]. But somehow the amount got deducted from my account and did not reflect in bill payment. So I was asked to make alternative payment which I did using Paytm (transaction ID - [protected]). Since then I have followed up personally with the branch 3 times for the refund of first payment but have been asked to follow up later. Either they are not willing or capable of doing it is my understanding, kindly help.
