Things with the systems we use to conduct calls were constantly changing, sometimes we'd only be given a short "training" on changes made in the system and that put a lot of pressure on making sure we were doing things correctly. Customers were DIFFICULT, constantly asking for things that were just nearly impossible, but that's at every call center/customer service job. Just don't go in thinking that because this is a "trash/waste service", they won't take issues that arise seriously. I had more angry customers call in than I did content ones.
