Deposit - Consumer Complaint for Impact Meters

Impact meters is a horrible fraudulent dishonest and inconsiderate of thei clients. They have suddenly out of nowhere increased my deposit by almost triple. Then they add this amount to my monthly consumption invoice this in it self is ridiculous, while I am busy disputing this with them they cut my electricity(bullying) and also add a fee becuase of oustanding service(this is illegal on customer protection act), my usage account is up to date. The only thing that I am disputing is the suddeb and without notice increase in my deposit and that it is added to my invoice as this is not consumption why is it added to my monthly usage invoice.
