Non existent Service of Vodamail

I have a vodamail e-mail address for the last ten years and get between ten to twenty e-mails a day. Since Friday 19th April 2024 I get message that my password has expired. Never received notification of this. I contacted the call centre and was given a reference number (A3-2EFT-QTDTG), with a promise that a technician will call and assist. Today, 21 April 2024, I called the call centre again and was informed that the technicians clock out on Fridays an may attend to my problem before 24 April 2024. Rediculous and pathetic on Vodacom side. I pay for a service and I need same urgently. Why did the password expire without prior notification
