Waste Management Inc locks you into rolling contracts. In order to cancel a WM contract you have to send them a certified letter 90 days in advance of the 'expiration date' of the contract.
If you don't, they roll you over for another contract. In my case, 36 months. To get out of the contract, you have to pay them a removal fee $100, plus 6 months of your last billing, in my case $906.00. This information may have been in the contract but was never disclosed.
Beware friend! Don't get into any contract with them.
Tell your friends. Deceptive company!
