@Wazeldab91 The name is only the Nickname for this forum. For MySwisscom the initial name should still work.
if there is further a problem, I advise you to call the hotline 0800 800800, they will fix this easily.
By the way, this is a "customers help customers" forum, this is not the customer centre of Swisscom. We as customers like you, have no access to your customer data. If you can no longer log in to MySwisscom, please call the hotline on 0800 800800 as written above. Nobody will answer you by e-mail.
Кстати, на форумах написание заглавными буквами считается криком. Мы не глухие. Пожалуйста, не повторяйтесь. (Something about writing in capital letters and what is the meaning of that 😀)
