Website:

My mother have ordered 3items and made payment of Rs. 1600 on 14/02/2023, and the status for delivery shown on the vendor portal is delivery will be made before 9 pm, but till date as on 15/02/2023, no delivery is made and their contact no. is all time busy and no response from them, further there is no option of cancelling order and no refund made till date, so they totally commit fraud and cheated me. After contacting them through Instagram they have replied me with just an excuse that they will look it up.
I want the refund
