Have a customer I truely hate dealing with. I don't want to try and renegotiate prices up to a point I think he will not pay, I just want to drop him cold-turkey. He is quite wealthy and I think hes been through most of the other companies in my area and would likely pay up. I don't want his money, he isn't worth it. I don't want to do this unprofessionally as we work by reputation and I don't know who he knows. I don't want to play the ignore his phone calls game, either. We have no contracts and neither of us have a debt/balance for one another. Suggestions? Advice is much appreciated. This will be the first customer I drop for something other than non-payment.
