There are many downsides to poor customer relationship management. First of all, a poorly informed or poorly served customer can quickly become a dissatisfied or even dissatisfied customer. The latter then tend to let those around them know and to spread negative opinions on social networks. This has repercussions on the image and reputation of the company. Second, poor customer service can lead to an immediate loss of revenue with the termination of commercial contracts. And finally, in the event of a major disagreement or dispute, poor customer relations can lead to legal consequences.
