*****ing from the consumer!

I have been closely monitoring our bills with Impact and one thing is NOT making sense to me.... We only have 6 lights in the unit with power saving globes, we only have a single fridge/freezer and a washing machine that is also power saving. Furthermore we only use our tv at night and to charge two phones, we also make use of our braai en gas stove to save on power and our water bill is only R300 can someone explain to me how such a small unit that only draws power at night as we don't use a kettle to push a bill to R2980???? You are ******* to say the least and all these clever clauses in the contract to increase a deposit to 3 times the normal rate and then come and disconnect power due to a deposit as my account has not been in areas!!!! You should be ashamed of taking advantage of people who only pay R6500 for rent but then charge almost half of that for utility??? Sies man!
