FNB electricity amount received incorrect

Horrible Customer Service.

On the 30th June I've bought electricity for Amt 1000.00 Rand.

The Token I received on message said : FNB :-) City of Tshwane. Elec Amt: R347.83. Vat Amt: R52.17. Meter: ######. Credit Token: ###### Units: 160.2kWh

I've been transferred to multiple people now and each time they put me on hold and say " They will check this issue " then i hold on the phone for at least 10 Minutes and then they put the phone down.

I've called multiple times over and over and over same results....

Is it even worth your time to try to get the rest of the 600 Rands of power ?

Will rather use a different Electricity divider to avoid this in the future.
