Robbing people blind using the lockdown as an excuse

I live in a complex on the Westrand. Triple M is a really unscrupulous company which is trying to bolster their profits during the lockdown. I live on my own and use a gas stove even to boil the kettle. Last bill I received was over 16 days +/- R290 I paid double the amount considering the lockdown. Latest bill comes and it’s almost R2000 over 47 days and the excuse given is that we are in times of lockdown. In past billing runs over 32 days I was billed for 304 units. 283 over 33 days in January. Despite the fact that I worked from home most of the time in December. I often work remotely from home, in March I was home from the 6th which is part of those 16 days billed at 108 units. What I find really strange is that my bill is suddenly at 732 units which is no where near my average consumption of the past 6 months. There are people in the complex who are being charged almost R5000 for their electricity bill. A resident who has a prepaid meter says her consumption moved to about R750 during lockdown it’s usually R600. They are a household of 4 and spent R750 on electricity in my one person household I’m being told my bill for electricity alone is R1281 ex VAT. There is something dubious going on here. How do I raise this with the competition commission?
