@kamphuis, when your account goes into suspension, you lose the option of making plan changes. Top ups/credit card changes need to be done no later than the day before renewal. Aside from that, it does look like the self serve portal is in a bit of a mess. I experienced that last night when I was doing some account administration. It could be from the recent maintenace outage, fix something and break something else. As already suggested, moderator team intervention will be need.
