Inconclusive data transaction(s)

<p>I ran out of data today and tried to buy some from the cellphone app as usual. It gave a 'fail' message. I tried then from the vodacom webpage, with the same result. I tried again a bit later. And again from my phone, a bit later again. All attempts gave an error message. Then I got 4 SMS messages on my phone, stating the the transaction has been successful, 4 times what I had intended. However, I still have no data. The call centre said I should wait 24h for the transactions to be confirmed. Whaaaaaaattt????????</p>
