Phoned been barred despite payment and new month

Received sms 'Your monthly Usage Limit of R221.06 has been exceeded. The line will be barred for outgoing calls until 2013-09-01:00:00:00 or until deposit of R235.25 is made. '
Payment came off my account on the 30th and it is the 1st of September. I cannot do anything in emergencies, not even retrieve voicemail. I was to in the sms and am a paying consumer.
