Furious!!

I joined this medical insurance in Jan and it was said I will receive the cards and everything after my first debit order and it went through end of Jan and again now but still nothing and their app keeps on telling me to confirm my login and resets my password every time I can’t proceed from that point. I enquired about both issues and asked if I can go see a GP with just the policy number no one bothered to answer I am starting to feel I made a mistake joining because they are just taking money and I don’t get anything in return. Could this be, be another insurance company ****?
