Blueyonder no longer able to sign in on imac or iphone

All the settings are correct as per the details within the email help section here.

Anyone able to help - password is 100% correct as I can log into the mail on VM site ok.

But 35 mins waiting for someone online - I gave up.  Shocking service utterly disgraceful, will be sending complaint to OFCOM.
