This is a common glitch recently where the system tries to give you the wrong plan from the one you ordered. In this case, it tried to give you the 12GB plan for $186, so the $120 it collected was not enough to cover it. Thus the suspended status. I believe all you need to do is go into your self-serve account and select the 6 GB Freedom promo (province-wide talk, global text, 6 GB data) and "change plan" immediately, since you have the funds available. This way, you'll have your service running sooner. Then, private message a moderator to get them to add the bonus 6 GB manually.
Edit: @mimmo is right (good catch). I'd forgotten about the block against changing plans on expired/suspended accounts. Looks like it's best to wait for a moderator's help to get your service running after all, unless you're willing to front another payment and get a credit back later, with no guarantee of success in the meantime.
