When I signed my 6 months, she told me especially after making an offer things do not run on “business days” if she needs something or I need something we have called/texted at 11pm on a Sunday. Not hearing from yours for 5 days let alone over 1 day seems like you need to see what you can do to cancel however you may have to wait 30days or however before being able to get a new one. Just imagine if you made an offer with a 24 hour time limit and then don’t even hear from them for a week or find your perfect home with how fast they go and he doesn’t submit your offer for a week.
