No prior notice then a summons

This is the first time I am hearing of any alleged arrears amount on my Vodacom account.

For months, no debit order has been processed on my side, and I have not received any prior communication from Vodacom or your offices — no email, SMS, letter, or phone call. Despite this, I have now been served with a summons without ever being given prior notice or invoices.

To make matters worse, I cannot reply to the email address provided, and when I try to reach out via WhatsApp, I am told that my details cannot be verified. How am I supposed to make arrangements or resolve this matter if my preferred contact methods are not working and no one from Vodacom makes the effort to reach me?

This situation is extremely frustrating and unprofessional. I expect proper communication, access to my account details, and an opportunity to resolve this matter without unnecessary legal action.
