I sent my security deposit on January 16th and it's still not cashed, do I have anything to worry about?

I sent my security deposit for my new apartment on Friday, January 16th and as of today Sunday, January 25th, it still has not been cashed. Since Monday was a holiday, I was wondering if I should worry that it has not been cashed. Should I call tomorrow to do a follow up?! I'm sure they got it, as they probably would have called if they hadn't of gotten it because I called on the 15th telling them I would have it in the mail on the 16th.|||I would not panic but sure you can call and ask them about the check.





Good luck
