Eskom is *****ing from our company

Eskom is the biggest **** I ever had to deal with!!! Since the middle of June our small company has been struggling to disconnect the power in the office, from which we moved out. No telephone calls, no emails to the customer service help! They received all our emails and rep****, they spoke to us on the phone and promised to terminate the account. But nothing has been done in this regard. The people in the call center are actually more rude than helpful. Two months after our first request to disconnect the account, the power is still on, our bill is growing. The problem is not only that the electricity might be used by someone else who moved in or will move in the office. Because it is a business account, our bills include the enormous availability charges, which create the main portion of the bill and the real consumption cost is only the 10th part of it. No matter if we use the electricity or not, we pay for the availability per day. We stopped paying in the hope that they will cut the power off automatically (that is what they suppose to do and did in the past). But not this time!!! The Eskom's activity is a real ***** - instead of disconnecting our account and returning our deposit, they keep the account connected and charging us until the total amount of our bill will reach the amount of the deposit. They do not even forget to put the penalties on the top. We had the hopes to get the deposit back because our financial situation is disastrous due to COVID. That was the reason we had to move out from the office and work from home. But Eskom has ****** our money!
