Remote metering services need to be held accountable!

I am absolutely sick and tired of RMS. I have had to pay unexpected amounts of up to almost R4000 in mysterious “back billing”. Whenever I try and contact someone regarding these astronomical amounts put onto my wallet balance they can never give me an answer. They are all either absolutely useless or they’re playing dumb to cover up the fact that they are falsely back billing. I am charged R150 A DAY for water and electricity and am constantly having to top up. When the amount I top up is never reflected on the wallet balance because they take 6% of any amount deposited. I have phoned multiple times a day to try and speak to a manager and she is never available. The worst company I have ever delbt with. ABSOLUTELY USELESS!!!!
