Fund Authorisation - C-***2

I am not happy with Authorization Manager Elliot Motsepe. AliExpress sent a refund into my account in April for a purchase I made in March. Absa was then meant to authorize the funds to reflect into my account however they sent the funds back to AliExpress. When I then enquire I am told to talk to the merchant. I do not understand the logic of reversing the funds back into the merchants account instead of clearing into my account where the funds are meant to be processed. I sent through all my communication from the merchant AliExpress to Absa however I feel like it was just ignored and I received a generic answer which is I should contact the merchant.
