Here is the story: We had duct cleaning service with Home Depot yesterday. Everything went well, until the technician finished the job and left, I realised the thermostat was off(blank screen). I called the technician, immediately he replied "I didn't touch your thermostat, it has nothing to do with my service!" I had no intention to blame anyone, I just wanted to resolved the problem! Next, we tried all the steps including to turn on/off furnace switch, on/off all breakers. In this stage I assumed that the thermostat has issues related to the furnace, because the furnace was not running as well. I called again the customer service number which I booked the service in first place, No one was willing to help! No apologies! They insisted the thermostat issue has nothing to do with Furnace, and of course they are not responsible for helping me out to fix the problem. I asked if Home depot could send a technician to take a look on the problem, maybe it was a small problem, but I was not able to find the cause. She said they will charge me $99 to send someone! She said "How's not fair if we didn't do anything with your thermostate?!" Are those people really qualified to work for a reputation company like Home Depot? In the end I have to call a friend who knows a little bit about electricity, he drove an hour to my house and resolve the issue that was caused by Home Depot home service people. The problem was the furnace was not closed properly, caused furnace not running, and of course the thermostat was off. Obviously, I was upset at this point: 1. I was told that the thermostat issue has nothing to do with furnace cleaning, because the technician didn't touch the thermostat (It's not on because the furnace was off, because the person who cleaned the furnace didn't close it properly) 2. They told me they will send a technician to check out the issue only if I agree to pay $99 fee. This is INSANE! The customer service staff attitude was rude considered that they were talking to a frustrated customer. Why the hell should I pay for anything that the problem was caused by someone who provided the service that I have already paid. With this being said, I'm writing this letter to share my frustrating experience and terrible customer service that I received from Home Depot. Also I have noticed the bill was paid to Steam dry Vancouver, assumed they are private company hire by Home Depot, which explains why those people are not professional. Thank you in advance for your attention.
