Residential address registered as business

What it means by a business address is simply that the last customer at that address had a business contract. They all use the same physical connection to the VM network, so it is only a paper exercise to change the designation. 

They will only connect one user at an address. 

The fact that it is listed as a business is an issue for me as I am unable to go online and get offers/deals since my address doesn’t show as being available on the Virgin network. Trying to renew my contract/take out a new contract is an absolute hellscape since it can only be done on the phone and I end up getting passed around from pillar to post, getting told it’s not available at my address and I can register my interest if I want. When I tell them the issue, I get passed to business and offered business broadband only since businesses can’t get broadband and tv packages, and I AM NOT A BUSINESS! 
Also, I’m not sure if you work for Virgin, I did (which is how I got my original Virgin contract on a staff account), and you are incorrect that “the last customer had a business contract” since we built this house and Virgin was only installed in our street a few years ago (around 10 years after we built the house), there has never been a business here, there has never even been another customer here.

So yes, I need this resolved as it’s giving me a headache trying to take out a new contract and having to explain to every advisor what the issue is since I can’t do it online.

Thanks.
