Street Style Store — Order cancelled but complete refund not received

I placed an order on 15/12/2023 for amount of Rs 3398 with EMI through snapmint. I made a down payment of Rs1133 on 15/12/2023 and one EMI payment of Rs 1133 on 3/1/2024.
Now my order is cancelled and I have not received my amount. I have been calling the SSS customer care but no one is answering. Only getting recorded answer.
Please get back to me as soon as possible.
