So what went wrong with this person to cause the problem?
CREATURES OF HABIT.
The problem is, the usual ways do not always yield good results, and here in our example you have reached such a point.
THEY ARE THE PROBLEM!
What is your body, your attitude, your behaviour, and your empathy, even compassion (or lack of it) saying?
What is it that you can not see from your perspective and situation that others can, and are you sure you are reading this person's communication correctly?
"The single biggest problem in communication is the illusion that it has taken place."
Today we are know that non-verbal communication is around 65% of our communication. Yet few people take time to learn such things as their own preferences, or discover how their own point of view can change their thinking, feelings and behaviour, and affect communication.
But this is what happens for many, we set the auto-pilot and do the same old things the same way, over and over again. Unconsciously hoping for different results!
BACK SEAT DRIVING
Thinking you know best in a situation without taking in all the information available can get you stuck. Worse still, when interpersonal situations are not really dissolved (but seemingly solved), you may not see the results of your actions right away. What can happen instead is results surface days or weeks down the road in the form of behaviour, and this behaviour is invariably not seen as the result of the past problem, but looked at as another unrelated issue to deal with.
The result again, blame and another missed opportunity to dissolve a problem, learn from a situation and create a better working relationship. Instead this is when people leave a job or get let go!
