Never Received my REFUND even after Canceling my order, Till now no refund received

I placed an Iphone 15 pro max order on 10th May 2024 using Apple Card, due to delivery date is long canceled on 12th May 2024. I got intimation like once order sent back to warehouse I will get refund but it took long and went till 29th May. But I raised a dispute 17th May2024 in my apple card to avoid payment for that monthly bill. I havent Received refund even after 7th June so.

I called apple and explain the situation after being in 2hr call with Goldmansach & apple team. I came to know that apple completed their side by generating invoice proofs and set their side refund as completed by assuming Goldmansach already provided me a refund by looking at dispute credit. as we know dispute credit is not refund its just a temporary credit available till that investigation proved.

So they both(Apple speclst & GoldmanSach) in call came to conclusion that I need to drop dispute so Apple can initiate a refund in 60 days, Today(08/08/2024) I'm still waiting for my money. if I call apple they are saying refund completed from our side call your bank & I'm calling goldmansach they are saying we havent received any refund from apple. I'm getting so confused what to do both are not helping even they are partners in Apple card. I pray god everyday for my refund $1300 its not a small amount to me. Please need some help.
