Dineout — Need full refund

I booked Chin Lung’s Marathalli restaurant via Swiggy Dineout. When I went there they said we are full no tables are free. So we went to another restaurant called Tropika.
There once we had completed our dining, I paid the bill accidentally to chin lung via Swiggy dineout. They I made the correct payment again to Tropika.
When I raised a complain to Swiggy, they noted it. If after I provided all proofs they kept saying we are trying to reach Chin Lung they are not reachable. So i decided to call Chin lung itself, they said they didn’t received any call and said they are willing to cooperate and will ask Swiggy to refund immediately. But Swiggy have been telling me wait for 48hours again and again.
The amount was 12560 rupees.
I have given all proof :
The actual payment proof
The bill generate
And the bill I paid to Swiggy accidentally.
I would request Swiggy to please look into this matter as early as possible.
This is the complaint Id [protected]
