Fossil Fuel Enterprises is a Weymouth fuel-oil company, and a 2023 Google reviewer from Braintree said a technician was at the house within 25 minutes of an emergency call about a leaking water heater. That 2023 customer wrote that the office called early the next morning and the techs had the tank replaced, "all in less than 3 hrs.," with a nor'easter on the way. The company's website says it provides home heating oil, fuel delivery, heating and cooling service, maintenance, installations and 24-hour emergency service on Massachusetts's South Shore. Its BBB page lists it as a non-accredited corporation with an A+ grade and 22 years in business. BuildZoom lists license number 195979 for the company. Its Massachusetts hvac license, 5680-SM-M1, is active on the state registry in David K Bishop's name. A 2022 Google reviewer asked for a technician to prime an oil tank and said the technician waited about 20 minutes without mentioning that a late evening fee would apply. That 2022 customer wrote that the charge stood with no negotiation, that customer service hung up on them twice, and that the account was terminated by email without their permission after they objected. The same 2022 customer called it the rudest and most unprofessional customer service of any oil company they had dealt with.
I made an emergency call to Fossil Fuel last night (Sunday evening). I panicked because my water heater was leaking quite a bit. The Tech was here within 25 minutes. He stated that he could tell by my voice that I was really worried. I needed tank replaced. He informed the office and I received a call from Fossil early Monday morning. The techs arrived at my house and had the tank replaced..all in less than 3 hrs.! It makes it more amazing that there is a north-easter predicted for Tues and they still fit me in! ⭐️⭐️⭐️⭐️⭐️🌟 Renate Braintree
Let me attest to the fact this is the most rudest and unprofessional customer service oil company I have ever dealt with. My experience today is for me to request the technician to prime my oil tank. When the technician came and I was almost home. However, he waited about 20 mins and he did not tell me anything about late evening fee will be applied. About 1week after, I found out the charges and called the customer service. She kinda explained everything since he waited for me and the time was after 4pm. I have to responsible for the charge. Honestly I did not really satisfy with the charge and she hung up my phone harshly, which was unacceptable. I called again nicely and other staff told me the same thing. The charge already been made and no negotiation. They will close my account due to my unhappy service. And I told them i will call back if i want to do so. After 10 min, they emailed me my account is terminated without my permission, which is ridiculous and horrible customer service that i had ever received. They hung up my phone 2 times. If you are looking for nice and professional customer service, please do not consider them. I will take my business where I am treated with dignity and respect. If you are looking for that do not order from Fossil Fuel
