I have seldom been so disappointed in any company, much less a LOCAL company. After waiting a few days for a service tech to come out, we had Dakota come over to try to help us with our radiant heater boile, which had stopped working. Dakota spent very little time trying to diagnose the problem. He determined that the problem was simply our the zone valves, and he went out and got two new zone valves. He installed the new zone valves, and then he fired up the boiler. It worked for the short time he remained, and he wrote up an invoice for $437.33, which I promptly paid. I asked Dakota to email or fax me copies of the invoices for the two zone valves, and he said he would do so later that same day. After Dakota left, the boiler stopped working again. We didn't notice it till that afternoon, when we noticed that the house was not heating up at all, and I checked the boiler, which was still dead. Also, Dakota never sent me copies of the invoices for the zone valves, as he had promised. I, Josh, then called ProTech. As no one was available – it was after hours – I left a message about the problem. Patrick and I spoke the next day, and Patrick was very confrontational with me rather than being AT ALL understanding or concerned. I questioned how long Dakota had actually been on the job, and Patrick said he had GPS records to prove that he had been on the job for at least two hours. I said it was my observation that Dakota had been on the job for very little more than one hour, at the most. Patrick said he "could" send me the GPS records, but then he never did so. I also told Patrick that I felt that their charge of $108 for diagnostics was too high considering that Dakota did not correctly diagnose the problem, given that the boiler was still not working after Dakota put in the zone valves. Patrick would not give an inch on this point. I told Patrick that for the cost of the labor that I had been charged – close to $300 in all – I felt that ProTech should send someone out to try to further diagnose the problem at no charge, at least for a certain period of time. Patrick was totally playing "hardball," however, and he said that he would not send anyone out to help me unless I paid a new diagnostic charge and new labor charges, even though the amount I had already paid had not fixed the problem. So not only did ProTech not fix the problem, but their main customer service rep treated me in what I consider a discourteous and unprofessional manner, making me feel like "the customer is always wrong."
