RMS Metering inaccurate

Moved into a New townhouse on 1 Desember 2020. We lived in a House with a Flat in Lyttelton. on average we consumed around 10-15 Units of electricity per day. (2X Geysers on the property, Live in cleaner with stove an kettle). Now we only have one Geyser, Gas stove and oven, also a gas kettle. but still our average units being used per day 15-17. This does not make sense at all. Sent multiple emails and phone keeps on ringing with no answer. In the meanwhile we have to keep paying for power we are not even using
