Business ProfileforAlberta Furnace Cleaning

My problem is with Alberta Furnace Cleaning for willfully withholding information from me to increase my charges in my home vent cleaning. I called the company to get my dryer vent cleaned and furnace and vents cleaned as my dryer was clogged and not drying my clothes. After explaining the problem the lady on the phone quoted me for ***$ to get it all set up. I agreed and we proceeded with the service. The techs finished up but noted that they did not clean my dryer vent when i asked about it. I was told that they were not instructed to do so from head office and that they couldn't do so if they wanted to because of it's location on the roof and there was snow build up. We rescheduled them to come back and i confirmed on the phone with the operator that I wouldn't be charged in addition for the missed vent. She agreed. Techs came back in a few weeks when the snow melted off and charged me ***$ with threat of collections agencies if I didn't pay. Reluctantly, I am forced to pay, as taking it to small claims would cost me more than it's worth. When speaking to the manager about this he gave me no agency at all and claimed that his employee wouldn't do that. I was lying to him about the experience and the payment confirmation. That I was never charged for my dryer vent in the first place. So on and so on. This is crazy to me. I feel like I have been taken advantage of and that this company is not transparent with there sales tactics. I would have never paid ***$ to clean my dryer vent/furnace, I would have gone somewhere else. I was lied to about the quote for service, and then lied to again when they claimed it was a free service visit on the second rescheduled service. This can't possibly stand. I am hoping that I can receive some help in recovering my ***$ that doesn't involve me hiring a lawyer. Unfortunately, i do not have a voice recording of the phone calls so I fear from a legal standpoint I have no ground to stand on.
