They are not taking phone calls, claiming that this is for staff safety. Aside from going against Boris' urging people back to work, it makes no sense. Other organisations are working phone calls from home.
Tofay they answered an email about a problem with an authorisation code with a standard response - a brush off - a phone call would be the obvious way to resolve this, and I know that they are sitting there!
Companies House is sinking in my estimation. They used to be my favourite Government Agency - for instance a request for an authorisation code, even late in the day, would be answered by mail the next day. Now it takes several days.
What a pity.
