Law abiding citizen....for what?!

I have just received a bill via email for 5k payable immediately for rates and taxes, however, I have never once received a monthly account. I called customer care and spoke to Nosipho, who advised me that the account was posted to us. Not once have I received this. I asked her if I could update my postal address or if they could email me a monthly statement and I was advised that they are only doing essential services and I must wait until after lockdown to change this as no one could assist. I asked if I could set up a debit order or make a payment arrangement, I was told I must go down to the city office to make an arrangement. She then told me that they have emailed me this account as it means they will be proceeding with legal action if I do not pay the account now in full. I also received an email from a *** email asking if they could email me statements as the post has been undelivered. So this should all tell them that I have never received an account, yet they can proceed with legal action against me if not paid in full but cannot update an email address? How is this acceptable and legal especially during a pandemic where people have lost jobs and income and where the post office has been closed and not even delivering mail. Pathetic service from a pathetic government, always trying to f**k the people!
