mytheresa刷卡問題 - 網店

昨天在mytheresa買了一雙鞋子
收到訂單成立的mail
也收到信用卡公司的刷卡簡訊通知
但今天卻收到mytheresa客服寄信如下

To avoid any possible credit card misuse, we would like to ask you to contact your issuing bank and ask them for the authorization number for your order. The provision of this number from you to mytheresa.com will allow us to compare the number with the authorization in our own system, therefore processing your order in compliance with both our security measures and your own personal satisfaction.

We kindly ask you to send us the authorization number via email to [email protected].

請問有人有收過這種信件嗎？
還是這是網路詐騙@@
