Worst service

I am utterly disgusted and disappointed at the service I've received thus far. I submitted a claim for a dentist appointment only to find out my banking details were not updated and I had requested discovery to update all my details almost 2 years ago. After speaking to an agent nd updating my email address and new number I was then transfered to have my new otp sent to my new number was transfered to vitality department. I then get told I must wait 2 to 3 days for my pin. Seriously discovery my claim is now on hold because I can't update my banking details. I need my otp pin so I can update my details. This is pathetic.
