I understand your disappointment.
However, How many deals or sales have ended up this way when a person is offered something better, maybe either cash up front, more cash, or just some better deal?
Not just about cues, but what if you agreed to sell your car or any other big money item over the phone but after you agreed to take that offer, someone else comes up afterward and offers you a couple thousand more? Would most people really think about their integrity and sell to the original buyer?
I know a cue is perhaps not the same as a car, but in this capitalistic society, I think money rules.
Wow. There are lots of people whose word is no good, but they rarely advertise themselves like this.
