Deactivation of SIM card without notification

Not sure why Vodacom deactivated and recycled my phone number without informing me or even sending me a message. This was after I had travelled and it was during the lockdown period where movements were not allowed. I am deeply disappointed after years of being with you.

It’s really frustrating to go to different service agents of yours, and even calling, only to be told that there is nothing they can do. How is that even possible.

This has caused great inconvenience as I am no longer able to use my WhatsApp with the old number.
