Where did you see that's for Koodo specifically? I personally did get a call over a month ago about it, but I wasn't interested, so I Didn't find out if I had to create a new line or switch over from Koodo to Telus. I'd send a private message to Koodo via Facebook messenger or dm via Twitter to see options for such a deal. Or go to a kiosk.

When I took ADT services I was told that you get $10 discount if you have Koodo or Telus wireless lines. I called ADT just now and they said they’ll send a request to concerned department.

Yea that's something that they should've applied when you signed up for ADT/Telus Smarthome Security but if you reach out to them they should be able to apply that like it seems like you managed to get started.

Hi Ritz,  Normally the credit would be applied after the ADT install is completed.  If the invoice is already produced, It can be applied to the following bill.
