Hi islaS1970.
Thank you for posting on the Community Forum, apologies for our delayed response.
Sorry to hear you've struggled to find out how to reach us internationally. Have you tried using our international number on +44 7953 967 967?
You also have the option to write to us at Virgin Media Sales Operation Support, Diamond Plaza, Daleside Road, Nottingham, Nottinghamshire, NG2 3GG.
Hope that helps!
Beth 🙂
