Security of R3367 MISSING and a new bill of R4624 - average spend R600 - R800

I have been living at the same address for 6 ye*****ach month, i photograph my meter and send it through to Ameer Arnold @ Eskom because I was tired of exorbitant estimates, I am one person. There are 2 months where i did not pay, July and August, as i called the number for my billing as the Invoice - stated R2120 which was impossible.The automated response said i was in Credit. I was contacted by Eskom in Bellville asking whether i had moved? I have not moved. My Security Deposit of R3367,00 is missing? 2 months Electricity does not equal R3367,00. Please advise WHO tried to cash in on the Deposit. Please advise WHERE the Deposit is. I received a bill for September of R590, which I paid. I emailed everything, including copies of bills and EFT’s, and was told my deposit would be put back. Now, if I call the number it says I have a bill of R4624 I have the meter readings and copies of all emails. I want my deposit back, and to be correctly charged for July and August. I am not emailing Customer Services again, as they don’t revert back, and request that I follow up. This is me following up? Query Ref ***
