Alberta Carpet Cleaning (Calgary)

My wife called the company ordering a carpet cleaning for a 4 bedroom house. They quoted $149 for the service and got an additional $20 off for a coupon that we have been asked to provide to technician. The date was set and the technician showed up in time, I went with him through the house and confirmed the price of $129 after providing a coupon. The job took about an hour to complete when a the end I was asked to pay more than a double the total of $270. I asked the technician for a breakdown and he told me that there are an extra charges for the closet which is part of the room , for the hall and stairs. I was telling him that my wife didn’t tell my anything about these charges and I couldn’t check this with her as she is not using the phone at workplace. I asked the technician why he didn’t tell me anything about the extra charges when confirmed the price of $129, he said that this is not his job and the customer service should have been advise us at the time of the order and there is nothing has to do but to pay the bill as the job is done anyway. He told me that customer service will credit us if they didn’t inform us about an extra charges and this is how it works and the bill should be fully paid. He handed me some ppwk to sign telling that is for the job that has done and collected the payment . I talked to my wife at her break a few hours later and she confirmed that no one advised her about the extra charges that may occur and once she called the office , they told her that she as the customer was supposed to ask it and the customer representative that took the order was on training and probably forgot to inform. They are note ready to issue a credit for a difference as they keep telling that the job already done. I filed a complaint on BBB and will take the company to the court for having them credit the difference. My recommendation to stay away from this company, this is nothing more than another rip**f, very disappointed.
