"Repair Service to Fix Gas Boiler - WM Henderson first sends out a tech who is not familiar with gas boilers and admits there is an issue but does not know how to diagnose it. I had to pay $89 for this. Instead of having the right person come out, I had to to actively call again to get someone else to come out. The 2nd tech diagnosed the issue, but wants to charge me the same $89 that I already paid. - and quotes me $380 for the repair - and has to order the part. I agree and then call back the next day to confirm part is on order - and they tell me the charge is $1,015. I asked to speak to a manager to discuss, and no one is available and no one calls me back. I bought the replacement part from a supply where house (confirming it works with my make/model of boiler) and it cost me $165. I have had other scheduling issues with them as well. Don't use them!!!!!!!!"
