My wife's prepay mobile needs to be topped up, but since approximately 3:00 pm today she has been unable to top-up or check her prepay account balance. When attempting to call anyone an automated message plays stating that an "IT upgrade" is in progress and to try again later. The Spark mobile service alert page at https://www.spark.co.nz/help/servicealert/mobileservicealert notes that there is an "PPHD" issue affecting some customers but offers no advice on when it might be resolved. Does anyone here know what a PPHD issue is and how long it typically takes to resolve?

I have not seen this mentioned in any forum yet, so does anyone else have the same issue and/or know if this is a widespread problem or if it just affects a small number of customers? My wife is stuck at the moment - she cannot make any calls because she has no credit, but is not able to top-up because of the outage. If this sounds familiar to anyone and they know of a way to top-up during an outage I'd be very interested in their response...
