If the subscription and phone are in name of your company the quickest way to get help is by calling our customer service for businesses on 0800-0403

If you're an employee of a larger corporation they will have a dedicated person/desk for this. 

If you have a consumer subscription on a company phone the quickest way to get help is by calling our customer service for consumers on 0800-0402
We can help with those you here as well but it can take a while before you get a reply.
