My story:
1. Change the plan from 90days/6Gb to 90 days/3Gb a few days before renewal. Future date the change. Anticipating the cost to reduce from $120 to $111, which is what the portal tells me the cost of the new plan is, I prepay the $111 amount. System tells me that it's not enough (need to pay $120 to renew $111 plan?). I chuckle at the glitch and leave it at $111 balance as it should be.
2. On the renewal date the service stops. Logging into the self service portal shows that account is suspended. $111 is indeed not enough to renew on $111 plan.
3. Having $111 balance, I decide to "change" the plan to $111 3Gb plan to shake out some action. First attempt is not successful, as the portal demands that I pay $0 more, which I can't find a way to do. But, after that a button inviting to activate immediately shows up. I activate immediately. The $111 balance disappears and the portal doesn't show account as suspended any longer. Looks like a success.
4. Still no service, contrary to what the portal seems to imply.
Argh...
