Still no refund after almost a month

Terrible service from Loot.co.za . I logged a return on the 28th of the December. The item was collected however I have still not been refunded. I have provided them with all the information requested when returning the item, including the account this can be refunded to. I called the call centre and they advised they refunded it into a closed bank account in error. I have still not received my refund or any feedback from Loot.co.za. I will be taking this further now.
