Vox Telecoms account issue

AC No. ***. A surprise message was sent to me on the 6th August that I have not paid my August ac. I immediately supp**** proof supp**** proof of payment! No apology! I then get further messages, that its the July payment thats missing. I supply proof of this payment. That was today at about 15h00! I then get further demands for immediate payment. I told them please resolve this before CoB today, at 13h47, otherwise Im onto Helo Peter! Obviously Bots or *****s are processing the customers messages? I now get another email my account is arrears! My account payments for 2024 were as follows, 30/1; 26/2; 30/3; 29/4; 31/5; 29/6; and 30/7! The phone number provided +*** is blocked/choked! So no interest in actually trying to resolve the issue!!!
