How do you know they were "estimates" in good faith? What makes you such an expert in his character that you are POSITIVE that he genuinely thought he would have that bass done next month.... or the next month.... or the next month.... or the next month...... or the next month..... or the next month....... or the next month..... amd so on and so on?
I don't buy that for a minute. I don't think they were attempts to get that guy off the phone or to stop emailing. I think they were intentional lies to get that customer to go away right now and let me "deal with it later".
Now, of course, neither of us can be sure. But you seem so definitive in your statements when you have NO IDEA if they were "estimates" or just lies to get the guy to stop calling for a few weeks (or emailing or whatever). You have no idea at all. But you won't even allow for the possibility that he was just gaffing off his customers intentionally.
Do you work for Zon? Do you have documentation? Of course you don't. And in that case you CAN NOT state unequivocally that he was only giving truthful estimates in good faith.
What a crock.
