Port/Migrate from GG to O2 - mistake with SSN

[unhumble]

Hello,

I received email with information that tomorrow :

The transfer of your mobile number has been scheduled for 
20-Jun-2023.

Unfortunately when I checked all information from that email,  I discovered that I've put wrong Sim Serial Number to the system. That number is without last 2 digits. Honestly I've had a problem with that when I filled online form. Probably I should ignore first double zeros. The result is that my SSN is without last 2 digits.

How can I easy fix that problem?

Thanks,
