we are into telecom customer service and after each call there is a message thats send to the customers asking whether the sub is satisfied with the interactions.

The target is 90% however we are able to get 85% only. There are customers who are ignorant abt the message and send "NO". There are customers who think that its about the entire service and then send "no"

We are not suppose to educate the customer on the message also.

Is there a way we can increase the CSAT scores
