In some past installations, a VM wall socket may not have been fitted and the connection may just be a trailing lead through the wall with a connector on the end.
If your property had its own VM connection, have a look outside and see if you can find the external VM wall box (usually brown or grey in colour) which receives the VM connections from out of the ground. If you can find that, see if you can trace the cables going inside to your property.
The 'Quick Start' offer just means that a connection was there in the past. Sometimes past occupiers remove these if they are not in use. If that's the case and, you really do have no connection, you will need to convert to a technician installation.
