Apple Valley Waste Management

I signed up with Apple Valley at the end of October for service beginning in November. They asked for 3 months in advance, so I paid them. They told me when to put my trash out for the coming week. I did that. No one came, so I had to call and remind them. The I get a bill for the entire month of October. Really? Are they that greedy? I just hope my experience with Apple Valley improves in the future.
