Hi @tudrussel
Welcome to the community forums
Sorry to hear that your property has been marked as unserviceable when your neighbours have a Virgin Media service. There can be many reasons for this, from construction issues, declined permits/permissions or the area itself already being at customer capacity and so we aren't accepting new customers in the area at this time.
If available, the sales team would be able to send out a spotter to access if the property is serviceable, though if this has already been accessed recently, there would not be the option to book a spotter unfortunately.
Do you live in a flat or a flat that was converted from a home or do you live in a whole home?
