Blocked my credit card after they requested an update of my personal information that hadn't changed. First, I was supposed to upload it based on a case number which was invalid. Then I was supposed to upload the documents via an Upload Center. I uploaded everything, customer support said it looked good. Today my card was blocked, turns out after the 3rd representative I spoke, that some information was put in the wrong line in two of the five formulars. To unblock they told me to re-uplaod but the process of documents could take up to 3 days. I am a platinum card holder who pays 60 Euros a month for absolute shameful customer support.
