Discovery Website and Phone App Issues

I have been trying the following: = 1. login to Discovery via the internet. This keeps telling me I will get an OTP. I NEVER GET THE OTP. 2. I login to the App on my phone. This works, however, I am trying to book a travel ticket urgently, however, the app cannot get my Vitality information so I can not book a ticket. Discovery app and internet site is the WORST 2 application I have EVER worked with. They are forever having issues and when you call the Call Center the response is "Sorry for the inconvenience" What a great excuse.
