You should put some systemic herbicide on the stems you cut, something with triclopyr. Vines store a lot of energy under ground, they will almost certainly come back and be harder to kill because they'll spread out.
I don't like using herbicides but this is one of those places where it will really help, and doesn't run much risk to other plants. Apply it with a brush to the freshly cut stems.

Thanks I did that, hopefully they don't come back
