Moin Moin,

for Point 1 Unidays is your contact point.

Hello @MK2612,

thank you for your enquiry in our forum!
To point 1, schluej is right - if you sign a contract with a dealer, he is your contact person. If you conclude the contract directly with o2, then o2 itself is your direct contact for your contract conditions.
Have you already contacted them?
Regarding point 2: have you already applied for the transfer? And have you already asked your other provider why the transfer has not yet taken place? What is the current status?
Regarding point 3: technical faults can always occur. Often, small problems are fixed on the site at the weekend, which is why some services are not available at a certain time. Did you try again and did the login/registration work?

Kind regards
Jessica
