Spree debited me twice for a single transaction

I ordered sneakers online. The total was R688. The order number was ********** 32. Spree debited me twice for this transaction. I called my bank (Standard Bank) to have the duplicate debit reversed and I was told that Spree has banked both amounts. The bank told me i need to call Spree and ask them to refund the duplicate debit.

I called Spree and spoke to a lady, Nishat, who told me that I have only been debited once and that I should send her proof that I was debited twice. I have since sent her proof showing her how the same amount R688 was taken from my account by Spree.

This kind of behaviour is the reAson many desist from online shopping. It is subtle *****. I want Spree to refund me ASAP. Thank you.
