An up-to-date account SUSPENDED???!!!

They canceled my security service, reason account overdue BUT I've completed their form on 14 Sep 2023 to change bank account for monthly debit order. They ame back end of Sep saying the debit order bounced and I must do EFT. October also bounced and I continued with EFT while on the other side everyone I'm speaking is promising to fix this bouncing debit order. I paid Sep, Oct and Nov via EFT. On the 6 Dec 2023 I received an email with statement reflecting the above payments but still showing account SUSPENDED. Now I would like my complaint - the email I sent on the 7 Dec 2023 to all those I've dealt with, to land on their CFO's office so he/she can see the incompetence of their staff.

Not happy Luvo
