I had to send my lg5 (which I had purchased in April) into repair because a) the battery performance (that had never been good) had gone to close to ridiculous and b) it randomly misbehaved (sometimes the screen wouldn't switch off and sometimes wouldn't switch on, plus sometimes the only way to end a phone call was by switching the phone off completely).
After dropping off the unit at the Koodo kiosk, I received an sms, stating that it had been received for repair. Thus, I somehow expected to also receive an sms once that repair was complete. Albeit, nothing happened. Now (about a week after it was returned to the kiosk by lg [according to the info in my self-serve account]), I finally went into my account to see what was going on. (A previous attempt to follow the tracking link I had received as sms was foiled because I was sent to a website that couldn't identify itself as Koodomobile properly, I received an 'unsafe website' message and didn't dare to proceed).
Here are my suggestions out of this exprience:
a) send automated sms when status is changed to 'repair complete' or 'item received at kiosk'.
b) update your website's security certificate
