Ridiculous service received

I purchased products online from Optimal Nutrition Hub for R789. However, on December 15, 2024, R2948.98 was reserved from my account by Optimalnutrientshub.cokekava. On December 17, I went to an ABSA branch to file a complaint and requested that they block the transaction. Despite this, on December 18, a debit order for the same amount was processed. I then contacted ABSA and was put through to Keanu Abkssol from ABSA *****. He assisted with blocking my account, but Optimal continued to debit my account even though I was told it was blocked. I have not received any communication from Optimal and require assistance in reversing all the amounts that were debited from my account.
