Why does LG600 show my old number?

I switched over my number and minutes to my new lg600. Everything is great except under my number it shows the wrong number. Everyone still contacts me with the old number which is great-I just wish my number would show up on my phone.

I contacted customer service and was told all I had to do was zero out the wrong number and input mine. They would not tell me how to do this and I cannot figure it out.

If anyone knows how to do this I would greatly appreciate your posting this information.
