Indian Oil Corporation [IOC] — had already paid via paytm but they also charged cash

Address:

Barwala Road ,Tayal Garden, Hisar, Hisar, Haryana, 125001

On 27/11/2019 at 06.29 pm i went to subhash oil company, barwala road, hisar (125001) and filled up my bikes fuel of rs.100 and paid via paytm txn id: [protected] and order id:#2019111618452500308410103714
And after that they said we had no receipt of your payment, but amount had already been deducted at the same time, and me also received 0.75 rs cashback.
After long debate they also charged cash of rs 100/- by telling that you should contact with customer care.
Now i want to refund my cash, take some action otherwise will sue on this..
