I received this email, but it didn’t work. I then called Swisscom. They confirmed to me that they had made this call.
I had to provide my address and lo and behold, after 3 days I received my gift. A little later I received an apology email. In this state that there was a disturbance. For this reason I couldn’t log in. Thank you. Maybe it would be good to inquire first instead of deleting everything. Many thanks to Swisscom
