Bill shows a New number I never Added or Requested

I assume you are a new customer and just activated your service? If that is the case, Koodo gave you a temporary number while waiting for you to transfer number over. As well, there is normally a "connection fee" if you ask a rep to assist. I recommend you check your selfserve and billing area, download the PDF bill and check the page 3, 4 of it for more detail.

Hi ​@Rythmal 

We have looked into it and we have sent you a PM to confirm some more details and further assist, please check your community inbox when you get the chance!

No Im not a new customer. Me and wife have been with koodo for few months now. Suddenly this month there is an unknown new number in my account. 

That is weird, I recommend you respond to the private message in the forum, sent by a Koodo rep above. Koodo might be able to figure out what happened. 

Since you may be a victim of a fraudulent transaction, I would suggest you to report this incident to the Canadian Anti-Fraud Centre, change the password for your accounts, and consider setting up fraud alerts on Equifax and TransUnion.
