No support for vitality baby programme

I have now been trying for more than a month to register on the Vitality baby programme. On the website, every time I submit, it gives me a technical error. I now called the number that is listed for technical problems, and the recording says due to high call volumes, my call cannot currently be taken. I tried literally every Discovery call centre number, and I keep getting the same message. I also tried to send a query on the website, but it gives another technical error. My pregnancy is passing and I still have not had any benefits for this seemingly wonderful benefit. Please assist, as Discovery's service is currently completely unsupportive.
