Hi. We are aware of some issues with the *130*3737*1# Moneyline loan service code. As for the others, they seem to be still up and running - all you need to do if you get an error, simply retry dialing the USSD code. Do see http://www.satechhelp.co.za/9612/Service-Temporaly-Unavailable-E152 for more on the common service error. Or kindly comment below with the particular service code you are having issues with including the kind of an error you are encountering and we will try and assist further.
