Incorrect final billing

Your final Koodo bill covering Jan 3 to Feb 2 after porting out on Jan 3 is likely a prorated final bill; Koodo charges for the partial service period up to the port-out date, plus the next full cycle in advance (common with their billing).
Log into Self Serve to download the detailed PDF bill (pages 3-4 show exact charges and dates). That'll confirm if it's just proration or something off.
Porting to Telus doesn't cancel Koodo billing automatically; you still owe for service used till the port completes (SMS should've confirmed success). If the bill looks wrong after checking the PDF, reply with those details or a screenshot (redact personal info). Also the bill might be different to the amount owed. 

Hi Robert,

The bill looks wrong after the PDF,

I attached a screenshot of page 3, you can see the services expired on Jan 3 but the billings for Jan 2- Feb3

Thanks Darius,

I will wait for the next invoice before paying the final amount.

​@byronlin  As the current amount is due this month, it is recommend to make a payment before the due date. Once the next invoice is generated, you will receive the reimbursement cheque for the adjusted amount.
