Typical Sales Job.. - Sales Consultant Service Fusion Employee Review

Management tends to over-promise and under-deliver. I was promised I'd be moved to another department before being fired for not producing in a timely manner. Mind you, I was only there maybe two months. I had a ton of appointments set up for the following week and wasn't on a write up or anything. I walked into work, was called in the office and told I am being let go due to performance. The day before, the manager told me I was doing great. So...... WTH?!
