The worst service- Alexander Forbes

Alexander Forbes has got the worst service. They are unable to sort a mere log in details. I called on Tuesday for them to change my log in details and I was told this is being actioned and it should be done in 48 hours , I should call again. When I called I was told the supervisor has a backlog of emails??!!! Whose problem is that? So customer can wait then until the supervisor reads emails? That’s so unprofessional AF!
