Socket installation needed - unable to book engineer appointment

I have just received by Quick start Virgin media package (broadband only).

I must have forgot to select the engineer visit option during sign up process to install the wall socket. My property used to have one but it was removed some time ago.

I am unable to arrange an engineer visit through my online Virgin Media account and can find no option to speak to a human about it on 0345 454 11111

Regards,

Cathal
