Saravana Stores — Return cash bill lost..Staff rude behaviour

I have purchased a saree worth Rs.1525 on 16.10.2023 evening for gifting purpose at Padi Saravana. since my friend did not like the colour, I returned it and received a cash bill on 17.10.2023 evening. Reported about this to the supervisor in the return counter and he took me to the first floor and taken my number and said will call in 1 or 2 days. But till now I didn't receive any call.
As I don't have any faith on the working staff, I want to bring this to management's knowledge.
The return supervisor was very rude and harsh to me. I felt insulted. But I don't want to loose my money.
I request Saravana Store PADI management to look into this and help me at the earliest.
