Replacement power cable for wall box?

Hi all, new here but hoping you might be able to advise. It would seem that our darling cats have managed to pull out and destroy the power cable that connects to our wall box just inside the front door. 
is there any easy way to sort a replacement fast? Currently about to travel home from overseas so can’t sit on a call to the helpdesk right now. Is this a common lead I can just order somewhere or I’m screwed till I get back and can try and phone them..? ;/ 

thanks!
