ZARA is *****ing money from customers!

According to my bank this happens a lot so I'm sure many have experienced it. I made an online purchase with ZARA on May 27th an obviously in order for the order to be placed, the amount of the item went off my bank account. I saw my bank balance drop with my own eyes. Cool. The item gets delivered 3nd June. Happy. Then midnight the 4th of June ZARA decides to deduct the amount again! I was livid! This is not the first time! I contact ZARA via Twitter because that's the only other way at midnight besides Facebook and guess what bull**** they tell me?! "We didn't double debit you, we only charged you once. It was a pre-authorisation. It's your banks fault" Absolute bull****! Im not an idiot, I can see when my bank balance goes down twice. If it was a pre-authorisation then my bank balance should not have changed! I even sent them video proof from my banking app but obviously they've been ignoring me ever since! No apology to an inconvenienced, ****** from customer. Nothing! My bank says they GET hundreds of calls like this about ZARA daily. ZARA is *****ing from customers!
