I have been asked by my VOIP provider to fill in a form to port my land line number to them. I contacted VM customer services and they were not sure of the postal address of VM. Can someone please give me a postal address that would need to be contacted in the case of a number port please.
Welcome to the Community, usually when you request a number port the company the number is going to will sort the process from beginning to end, there isn't an address for you to contact in order to request that.
I'd recommend speaking with the company you are moving your services with to ensure they are getting in touch with us to arrange this, if possible.
