Reliance Trends — Complaining about my refund

Address:

Mahabubnagar 509001

On 4 july 2023, i went to puchase a top from reliance trends mahabubnagar
They show me a scanner for payment
I scanned that but didnt pay for 2 min.
After 2 min.i paid on that scanned image to reliance but they said that as same scanner is not showing on screen now thats why they cant give me my top nor my money back
Then they raised a request from their side for refund
Today 19 July, but still i didnt get my refund of 559
Kindly help me through this and provide my refund
