We can't buy water because Meter number is invalid

We just bought a house in lion pride. Prepaid meters are lesira's and we found a dam next to the Meter(leakage) and the Meter is not even functioning. It is completely off,we can switch it on.

To make matter worse,we are currently sitting without water as we can't buy water online and on few retail stores that we went too.

Every were we go our Meter number is invalid...
