Reliance Home Comfort

My furnace broke down in Dec/2023 so I contacted Reliance Home Comfort for inspection and replacement. A sales rep was assigned to me. I initially agreed to rent the furnace but decided to purchase the unit instead within the customer remorse period stated in Reliance's contract. So I contacted the sales about my decision. She offered me a discount price on the furnace purchase if I would buy the heat pump from Reliance too. I agreed to take the discount and went ahead with heat pump purchase from Reliance. The heat pump was installed in Feb/2024 but charge for the furnace never showed up in my bill. I reached out to the sales through email, text, and phone call but never got any response from her. Therefore, I contacted Reliance customer solution on 5/12/2024 and was told to get back to me after speaking with marketing department. It's been almost 2 months since and 5 follow up emails after, I got no answers from either party. I've been completed ghosted! Reliance has started billing me for the furnace rental and completely ignore my request to resolve the issue. I have no faith in this company. Be very careful about their offers and make sure you obtain a second opinion before making a final decision.
