@EZR Quebec usually have better deals than the rest of Canada. This is one odd time that good offers do not apply for Quebec. But trust me, you will see some much better Quebec only deal soon
I believe you can still get this deal if you are willing to change the phone number to other province if you really want to get the deal.
Your screenshot is showing that you've subscribed to the 90 day/$39/30GB plan and it will start on June 20th, so no need to contact support? edit: adding the $39 price point is the give away that you'll be on the 90 day vs 30 day plan.
edit: okay, I see it says 20GB, very odd. Sorry about misreading it..
@Handy1 Hmm...that's curious because I'm able to see all the plans including the $15 plan (I'm on) when clicking the Change Subscription link, which makes me wonder if the $15 plan is coded differently and hence the reason I'm able to view it..
Select the $45 one. It will ask about next renewal or now. Choose next. It will go to a next page. See if it says $44 then. Then if you like choose the 30 or 90 days. See that it says $117 or $44. I just checked on the website change plans and I see the $44. So it's odd that you're not.
Adding - are you in or do you have a Quebec number?
