Missed Deadline...

So the people had until 5:00 today to respond to my offer and they failed to do so. I was a little huffy with my realtor because I didn't hear from her all day and finally called her at at 5:45 and had to leave a message. Boy was I frustrated not knowing what was going on...finally she called around 7:00 and said that the other realtor left her a message and she was unable to get in contact with the woman who is in charge of the sellers "trust". So, now I can legally back out if I want to, or I thought just because they failed to respond to the first offer I should make another offer, lower than the originally! Ha, ha!! Anyway, it is annoying!! Is this a sign of things to come???
