Vodacom cancels contract 5 years after we went on debt review.

Vodacom cancelled my wife and daughter's contracts on Tuesday, 1 August 2023 without notifying my wife.

Their excuse is that they have cancelled the contract and deleted the numbers because they were informed that we are on debt review.

We have been on debt review since 2018 and my wife was able to upgrade twice since then. Vodacom told her that they were notified about our debt review status on 26 July 2023.

She has never missed a payment on her contracts as it was part of our debt review budget and it was paid via debit order.

How can Vodacom simply cancel a contract without notifying their customers in advance?
