Business ProfileforShred-It, a Stericycle Company

I contracted with them to come to my place of business to shred some boxes of documents. There was very little discussion of box size and I have used the service in the past without issue. When I received my invoice, which I had to request after getting a late notice because the original invoice was never emailed to me, I discovered that I had been over charged by 11 boxes. I tried contacting my *** to discuss the overage and he refused to return my calls so I called the company customer service line.I was told that the extra boxes ***resented the larger boxes that I had included in the pickup. I explained that I was not told that I would be charged double for the larger boxes and that in the past there was only a slight increase for larger boxes. I was told that they understood my frustration and that the extra boxes would be removed and to wait for the updated invoice. I never received an updated invoice and the online balance didn't change so I called to verify that the account had been updated. I was told that the adjustment had been refused and that I still owed for the overage. I did not accept this result and asked to speak to a manager. They said one would call me, but no one did. I called 3 times looking for a manager, was told they would call and they didn't. I finally spoke with someone who said they were a manager but they appeared to have no authority and ***eatedly said they would have to check with their manager and call me back. I have not heard back since.
