Leapfrog Roodepoort - Just deducting funds from account

Leapfrog Roodepoort - They have a total disregard for the Treating clients fairly & NCA act. They don't respond to emails. Since December 2021 i have been asking for my usuage statement in regards to water, to date i have not received a response. Today i received an debit order notice stating that they are going to deduct almost R500 from my account tonight due to them guessing the Electricity usuage and them being too *********** to do their job to get the accurate statements from the municipality on a monthly basis. I have received no communication from them prior to receiving the debit order deduction notice informing me about the mess that they made. They are just deducting money from my account without my approval. In 2021 the same thing happened they guessed my Electricity usuage. I asked for my Electricity statements. They picked up that they under charged me and that i still owe over R1000 over the period, because they didn't put the accurate amounts on my invoice. I paid it but now it is happening again. This company is a joke, they just do what they want with no regard towards the regulations. This company just deducts funds from accounts when they want to and how much they want to. They are too lazy and *********** to do their job and the customer must pay and suffer for it. How is it fair that a customer must pay a lump sum amount for months worth of electricity that they guessed incorrectly? If the correct amounts was given each month the almost R500 would have been splitted. I don't mind paying what i am due but i do mind having to continuously pay lump sum amounts due to lazyness and negligence and then them not even having the decency to discuss their mess with me first. I don't have the funds to continuously pay these lump sums.
