Waste Management Fresno ca, houston, tx I have been slammed with charges from previous owners account houston Texas

 We bought a property 8 months ago. There was a 40 yard dumpster full of trash in the back left by the previous owner who we found out later is a total dirt bag. We called waste management and reported the dumpster and asked them to pick it up. Them came over and refused to haul it saying it was too full. Being the new owner and wanting this massive trash can off my property I climbed into this dirty thing and removed trash getting it to what they had requested. I called them and asked them to come get it. They said they had no dumpster at my property it had already been picked up. I went back and forth with these guys for months. I finally called them one day and advised them I would begin the labor I intensive process of removing all trash from there Dumpster and I would recycle the metal dumpster itself. They came the same day and took it. I was so happy. Several months later I started a service with WM for a weekly 3 yard Dumpster. They immediately sent me a bill for $970.00 for the previous dumpster. I called they said I was recorded and through voice analysis they determined I was the person who ordered the old dumpster. I called ******** and demanded they remove those charges from my account. They agreed and said they would remove the charge and go after the old owner. They appologized. Today for the 3rd time I have spoken to WM collections and we have had the same conversation. They are unable to get the old owner because he left the state and has given an attorneys office as his forwarding address. The old owner never changed his address. We send his mail back regularly with not at this address. WM is simply attempting to wear us down for the old owners bill. My next step is to sue for storage of their dumpster on my property for roughly 5 months and attempts to latch on to my good credit as a form of extortion.
