Vodacom Cresta

We did not renew our contracts with Vodacom as we emmegrated to the UK. We switched over to pay as you go. We asked for afvice at Vodacom Cresta and a month before we left for the UK the gentleman adviced that we must come back on 1 May to do roaming on our phones. We went back and another gentleman assisted us and said we do not need roaming as our numbers has been changed over to pay as you go. All we must do is make sure we have airtime on the phone and that we make 1 phone call a month. We cannot even make a phone call or receive any sms's. Which is a big problem as we cannot receive notification codes from our bank accounts and we need to be able to make payments with our credit cards. And we cannot even phone to try to get roaming. Vodacom please sort this out.
