Hello,
If you have not received the purchase confirmation email and have also checked your SPAM folder, it is possible that the purchase did not go through successfully and what you see is only a pre-authorization for the payment.
We invite you to wait for your account statement and try the purchase again. If you have any doubts, you can contact us by phone at 0848 44 66 88 (CHF 0.08/Min) or +41 51 225 78 56 (from abroad) or via live chat, and we will check for any orders under your name. Here on the Community, due to privacy reasons, we cannot do this.
I wish you a nice day,
Chiara_S
