Take the s off the https and you get to what they probably intended.
The problem with some of these surveys (and to clarify I'm not referring to plusnet) is that they fall on deaf ears anyway, and any complaints are handled in the wrong way. If I have a problem with customer support with a company it's almost always due to the company attitude/management, and not down to the actual person i've dealt with, and I fear that the feedback from the surveys is acted on in the wrong way and to the wrong people.
