Unhappy and robbed customer

On the 6th of September I placed an order worth R1685.84 and on the 28 I receive a notification from my bank saying I will receive R244 refund from Airydress I thought 1 of the item I ordered they did not have it,when I made enquiries they said full amount was refunded but sadly I only received R244 and I never asked for refund I was waiting for my order I am yet to receive an explanation as to from whom only God knows.
