My first job was on the support phones for an online bank. It was pretty much used as the only place that would take people who either had too poor credit to go anywhere else or were new to the country and did not have paperwork required for normal banks. The job itself wasn't anything tough but it sure was emotionally taxing. The people who used it were pretty much the worst off people in the country yet our fees were so much higher than other banks, re routinely had problems on our end that made people lose money through no fault of their own, and just generally screwed people over. I would say the aim of my job at that time was not to solve people's issues - I had been warned about spending too much time helping people, but moreso just to get them off the phone. The only statistics that mattered were how many calls you got through and whether you remembered to say the company mandated call opening line, closing line and a few bits in between. How well you solved issues simply didn't come into it. A large part of the job was pretty much just being a wall for people to yell at - they would call up, have a problem that is clearly our fault, I would tell them I can not do anything, let them get angry for 5 minutes and then revert back to company approved procedure where we pretty much just tried to get them off the phone and eat the losses and stop calling.

It was very disheartening to see the people who needed assistance the most getting screwed over the most, with nowhere else to turn really. That isn't even mentioning how terribly the staff were treated, how much unpaid overtime there was through no fault of anyone working there (servers going down etc.), the poor hours where you would start wildly different times each day, regardless of what time you finished the previous day (often finish at 10, back in at 7 - it was just luck of the draw)
