No refund for goods returned to the seller and further deductions made on bank account.

I bought a wig on the Haircity website on the 10 October 2020 (Order Number: 39753). When the wig was delivered on the 12 October 2020, it was too short and not as I expected, I immediately notified Hair City on the 13 October 2020 to collect the wig and refund me. The wig was collected and I was told that the deposit of R600 paid will be refunded within 7 days. It is the 6 November 2020 and the refund has not been made to me. Furthermore, since the wig was going to be via PayJustNow in three instalments, the second instalment was deducted whilst I have returned the wig. I need Hair City and PayJust Now to refund me the R1200 they have deducted with immediate effect. The goods have been returned back to HairCity.
