Double debit

I had a bad experience with Zara twice when shopping online. My bank account had been debited twice for the same purchase, on 2 different occasions. I had to go inside the bank to reverse the debit and it is such a mission, as the Zara headquarters needs to be called for this nonsense. Please fix your online payment system or cancel the online option if this is what will be happening to our bank accounts. The reversal option reflects very bad on our credit score, please sort this matter out so we do not have to be going to the bank for unnecessary things. I am a very unhappy customer at this stage🤮😡😤, as I never thought this would happen to me in less than a month.
