Hi there @xavmac02!
Welcome to the community :).
Can you please clarify what you mean by "got a new number on the same connection"? Your Fido number can only be associated with one Fido SIM at a time and vice versa.
That being said, we'd like to have a closer look at your account to review the changes made. Sending you a PM right now!
Were you able to get this sorted out?
Do you mean that you intended to add a new line to your account but the SIM card for that new line was activated on your existing line instead?
Let us know if you still need help!
