Bad service

I joined this medical insurance through Hippo and I am really not impressed with how the admin side of things is run.

Reason for me to join was for my kids to be covered but I could not include them since I don't know their ID numbers off by head, but I had their date of births. What kind of system rejects a date of birth?

I was surprised by a debit order then I contacted flexicare direct to question why was I the only one covered on the insurance and I was told that a hippo agent will call me, I am still waiting.

I submitted my kids ID numbers via email but they are still not covered and the next thing I will be told about a month waiting period for them. Why am I debited money that covers only me? What is the point?
