Sears Carpet & Upholstery Cleaning

I had Sears Carpet cleaners here 2 weeks ago. Paid for 3 rooms hallway, stairs for 129.99 extra 100 for deodorize .I founds lines and triangle parts still looking dirty.called the office and they pleasantly arranged for a second visit.
This time the Tech was unpleasant raising his voice and saying the lines were normal and carpet was nicotine stained and would not be removed. Despite my explaining that the carpets had been cleaned once before after smoking had ceased in the house yet did not have the marks I had this time.
Said this time carpet cleaned in one direction and excess water not removed ( this is what causes the Lines) carpet would take 24 hrs to dry.
Next time I'll use a Carpet company not SEARS
