Use until: until two or three days ago.
If you're writing, use or: two or three days ago.
If you're quoting a conversation or writing dialogue, put a comma between two and three: two, three days ago.
An ellipsis (. . .) either means that unneeded words were removed or that there was a very long pause. A dash (-) there would also signal a very long pause. A slash (/) would be meaningless.

tufguy, this is not a productive thing to do. You've done it to me too. It makes you look as if you haven't read half the posts. If you're going to post an amended sentence, at least write it with the information you've just been given. I notice you've done that in post #5, and then you post a 'correction' that you know to be wrong. Why?Correction for post# 1.
