Pluspunten
The work itself isn't that bad talking to customers is certainly something you get used to. It can be quiet so there's some down time to just work on emails or speak to colleagues but most of the time it is busy and the days go by quite fast.
Minpunten
You'll be asked to work overtime a lot and you might feel the need to say accept. If you're a yes man they will take advantage of you so you need to learn to say no. Staff are friendly most of the time but they are poorly managed, there's not really a hierarchy like most jobs, instead everyone who isn't new is your boss and they all disagree with each other on how to run the place. So you'll find that there's inconsistencies in what your job requirements are. You'll also find the issues that are reoccurring that customers complain about are never fixed for months if not years so you'll eventually just become desensitized to it. Basically have to accept even though they're not a large company your impact will be small and things never seem to really change that much. Not a lot of room to move up either so if you need a pay rise better to go some place else.
