I don't know what there is to do other than to be aware that the combination of your name and number (and maybe some other details) are not private, so there's no reason to trust anyone just because they know those things.

As far as seeing what was leaked, you could find the data yourself (but I'm uncomfortable giving instruction on how to get it). It would be nice if it was possible to extend the tool to be able to send the information for a number to the number (because that's the only way I can think of that demonstrates ownership of the data) but that can't be done for free and it therefore seems too complicated to set up.
