Inaccurate statements

Hi. I have a big issue with eskom. I have phoned and emailed several times. I get no responce or solution. They put our account on hold for 3 years. I paid every month. I received no estimates. This year march i get a account of R63000. All the fees included for 3 years. I paid it...then june i received another account from june 2016 to june 2017. Everyone keeps tellings me its due to estimates...but there was never estimates and apparantely the system at eskom and the statement that i receive each month is 2 different things. I should ignore my statements because its not accurate. This is eskoms reply to me. I have to pay another R43000 because i am a risk and need to pay R10 000 deposit also but im only renting the house.....they came and switched off my electricity about 2 weeks ago!please help as eskom cant assist me.
