Help with my WIX site

I need some help with my site on the following please:

1. Social media links are not working, even though I have the correct URL for both, for instagram it directs to another business, for facebook it says page not found.7


2. Connecting my newer domain and email: had to change from Thrive fitness website & email so they are currently on a redirect, however I want to shut my old domain and email down now, to avoid paying for both.

These could be very simple solutions but I have had no success or patience! I hope you can help.
