They have my money, I can't make calls...

<p>A week ago I suddenly found I could not make outgoing calls. The call centre said my account was in good shape (R880 airtime credit), no problems. They suggested I reboot my phone. Since then I've had three or four conversations with mystified agents. They trot out the same advice -- try manually selecting the network operator, try rebooting. After dozens of attempts, this clearly is not going to work. The problem was 'escalated' to a specialist technician... who gave the same advice. The problem is exactly the same if I put the SIM in a different phone, so clearly it's not anything to do with the Android settings. Meanwhile I have to make other (inconvenient) arrangements to make calls and I can't access my airtime credit. Vodacom have been singularly useless in sorting this out. Having been a solid customer for about a decade, I expected more.</p>
