Waste Management Lied about Required Service Houston, Texas

I recently built my own home.  In the process of setting up or building I was told by Waste Management that it was required that I rent a dumpster from Waste Management because the city in which I live used Waste Management for rensidential pcik-up.  

I was given a figure but when on the day I asked for delivery of the dumpster the price was inflated which angered me, but I believed I had no recourse.

Shortly after the dumpster arrived I noticed that contractors in the area did not have the Waste Management dumpsters and asked why they didn't and was told that they were not required.  I was livid and called Waste Management and demanded they pick up their dumpster.

I paid over $400.00 for the delivery of the dumpster and thought I was done with it.  About two weeks later I received another bill for over $1,100.00 and refused to pay it.  Since then I have been badgered by them through email, telephone, and the regular post.

This is not an honorable company.  Do not do business with them.
