Refunds and empty promises

We placed an order for pivot door on the 20-07-2024 - on the 21-07-2024 at 11:14am we cancelled the order due to the lead time that had changed on order confirmation. On the 22-07-2024 1.37pm Sharconia Seapose confirmed that our refund will be done within 7-14days. On the 12-08-2024 @10.39am she followed up to see if we received our refund which we didnt , on the 15-07-2024 - she attached a proof of refund done - which shows it was only done on the 15-08-2024 , we now however have Marketplace calling to find out which item we want to return and have refunded? What are you guys doing and is the Proof of the refund that was sent even legitimate?
