Horrendous Online Banking Service

This is by far the worst online banking service ever.Clydesdale Banks are shutting branches all over the country and if they do not improve their online banking to a very high standard they will have no customers left .
I have had a Clydesdale Bank account for over 20 years and just recently decided to register for online banking 6 months ago, big mistake!
The first details they send out by post for you to complete your login details did not work and after contacting customer service they said they would send another one out. Success in logging after getting the second login code delivered, but short lived. Two days later I could not log in as it said I had entered the wrong password, but I had not. Went through the process to change my password only to be frustrated that a letter would be sent out for me to complete registration details to update/change my password.Once again I am back online. This has happened 3 times.
Now today when logging in it asked me for the 11th character of my password ?? I only have 8 characters. So I went through the process to renew my password, filling all the details required and requested the activation code to be sent to my mobile, after clicking this option I got the message
