Can't buy data bundles

My 30-day data bundle for a router/hotspot expired midnight 28 June. At 00:30 I loaded R402 airtime, then tried to convert it to 5Gb data @R399. All efforts via a separate connection through Mobi website, Android app, full website were met with a string of error codes and messages such as \not enough funds available"";NULL;NULL;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; ***;867026;712121;15;2;0;1;0;0;2;NULL;NULL;NULL;15/06/27 10:00;15/06/29 7:21;Shocking service, management and food;;;***;Miserable waitress<br> No croissants available until 11 on a Saturday morning.<br> Hair in sausage.<br> Cold eggs and bacon, but sausage and chips hot and toast lukewarm.
