Pros
You actually learn a lot from all the processes in place. Be it product, success, sales, marketing, support and sales, if you ignore the product deficiencies and just concentrate on the processes, they can be good for you career.
Cons
For every negative review, there will be uber positive review posted. That is enough to make you understand the internal strife of the company. Agreed Customer Support needs to support better. It is the same breath as Sales need to sell better, Marketing need to market better and Product needs to build better. The company is going through an identity crisis, looks like there's no more forward thinking but just hoping for the best. The main leadership team are not leaders, instead listening to flavors of the months. Or whoever sells the dream better. I'd stay away unless you see proper reviews posted here, and you can obviously see what's fake and what's not.
