I have a customer that we have worked on a project for a year. The manufacturer made their windows wrong seven consistent times. We have been done with our work since July 2021. and finished the warranty work last Thursday. He has taken a self proclaimed discount of nearly 5000 for pain an suffering because of manufacturing mishaps. While waiting for warranty glass from the manufacturer. We initially took the down payment by credit card but have change our policy on credit card and not processed since because of fees for the construction industry. This customer is insisting on paying us by credit card even though his final payment mode of acceptable payment was discussed prior to him and I have told him over and over acceptable payment are checks, cashiers checks or cash. Is filing a lien the answer? being that I spoke to card services our merchant and our account is dormaint for non use. and will not fund us if we run the payments.
