Zaxx Cabinets

Problems from day 1.
Zack came to our house for an estimate without confirming the appointment time, and so he arrived at an empty house calling me while I was at work, telling me that he was there. We «rescheduled.»
He came back for the estimate and showed up an hour late (though he did call first).
We ended up scheduling a date for the cabinets to be installed. He informed me that we needed to pay half before the work started, and the rest after the job was done. He instructed me to call and pay with a credit card over the phone. A few days before the installation date, I called him to pay, but no answer. I left a message. I didn’t hear back from him, so I emailed him to make sure he was still coming Friday. He responded, saying that I didn’t make the down payment and that he would «try to squeeze me in,» or he would have to come Monday. He also said that he didn’t call me back because my message didn’t specify that it was regarding payment. I took Friday off so I could be there when they were working, and I told him that Monday would be inconvenient. Why couldn’t he just call me back? Why do I have to drop certain key words for it to be worth his while?
We emailed back and forth a couple times. He ended, stating that «something seems wrong with this situation,» and that he didn’t want to do the work anymore because I was «scaring him.»
Zack is a joke. I can’t possibly have been the only potential customer that he’s left high and dry.
No communication. A complete lack of professionalism.
