Express Sewer & Drain

I called Express drain and accurately described what needed to be done to clean my drain as had same thing occur about 3 years ago. I told their operator that they would have to go in through a vent and told her they had an 89 dollar special which I would like. Their booking operator said that that would be the price and that she would make sure to put that in her notes. When the technician arrived he said NO to that price and said it would be over 200 dollars, which I refused. He said that that price quoted was a mistake. and had the office call me . The lady I spoke to which was a different one that the one I spoke to originally kept cutting me off all but called me a liar. I KNOW what my original conversation was and how specific I was as to what I needed. As far as I'm concerned Express Sewer is nothing but a ripoff trying to give you one price and then changing once get on the job. I would recommend that all potential customers stay clear from this unscrupulous company. When I told them I would leave a negative comment here on YELP they said to go ahead as they would dispute it as they have done with others in the past .
