Do I *actually* need an engineer visit?

[#1]

I have just moved into a new flat that has an Openreach Master Socket 5C (see attached image). 

When I signed up for Fibre 74, I was told I wouldn't need an engineer visit. I am now being told that an engineer visit has been booked for next week.

I called Plusnet to query this, and a customer rep said an engineer would be needed to 'check I have the right Openreach socket'. I explained that I do already have one, and described it to her. I was told an engineer visit is still necessary, but with no real explanation as to why.

I'm pretty baffled. Surely this is a waste of time for everyone involved? I anticipate that following the setup guide for the Plusnet Hub Two will work straight out of the box, given that I have a suitable socket.

I suspect it's one of those generic messages which get sent out.

If things go well when the connection is made then you'll not get a visit. However, if a fault is discovered they may need access to the Master Socket to run tests.
