Quote them some of the information from the ACCC website about non-delivery of services when you are next in contact with them…
In particular…
Under the Australian Consumer Law, businesses must not accept payment for products or services if:
- they do not intend to supply them
- they intend to supply materially different products or services
- they know, or should have known, they would not be able to supply the products or services within the timeframe indicated or if no timeframe was provided, within a reasonable time.
This could action them into issuing a refund for direct debits they have taken when they knew that the service could no longer be provided.
