First of all, it would be simpler in the call centre to press “1” for citizenship, “2” for immigration. When you want to have the status or the change of address, for example, if you are going to make the change of address you can do it online, but refugee claimants cannot.
I believe what they need to do is improve the simplicity of the use of the call centre and the simplicity of the website and have the same communication.
