Discovery Maternity 'Benefits' - No real benefits

The Discovery Benefit as per the brochure: "You have cover for up to five pre- or postnatal classes or consultations up until two years after birth, with a registered nurse."

A week or so ago I claimed for pre-natal classes. According to the new Discovery Maternity Benefits (shown above) I am allowed to claim for this out of the Maternity Benefit without having to fund it out of my MSA. Discovery however decided to pay it out of my savings account even though the classes were provided by a registered nurse and my wife is registered on the new benefit (I ticked all the boxes).

I decided to query the claim from Discovery and this was the response: 'Due to the service provider not using the correct code the classes were funded out of your MSA.'

So even if I followed all the rules set out be Discovery, I still did not receive the benefit just because of a simple code.

While having this conversation with the call centre agent I asked them to provide me with the correct codes so that I can double check with the service providers as to avoid this issue in future. I was told that the codes would under no circumstances be provided to me.

How can I ensure that the right codes are used by the service provided or how do I select the correct service providers if Discovery is not willing to assist?

Yet again it feels like Discovery market these amazing benefits but at the end of the day the consumer sits with the bill. They never offer to help but rather force the blame on the consumer.
