It's Bait and Switch. Thinking we could use them due to the special offer, the bill was $171.00 over the written estimate we received!!! When asked, they responded that cleaning 3 area rugs (which we have) of a smaller square foot area is more expensive than cleaning 3 rooms with wall-to-wall carpeting of greater square foot area. And, when finished, they did not replace the rugs over the non-skid runners.
