Your post is nothing but admission of your failure to demonstrate professional behaviour. Under such circumstances expecting professionalism from manager, how far would it be proper, that I leave it to you. My analysis of the post is as below:
a) If you were required to attend court hearing, then you should have applied for leave well in advance. Since you did not intimate your manager in advance, you had to absent yourself exactly when the feedback session. Is my interpretation correct?
b) When you wanted to inform about your absence (leave) that time the battery of your mobile phone was drained out. This shows your cavalier attitude. Why you did not charge the phone or keep power bank besides you? Why you did not use someone else's phone or call from public telephone booth?
c) You say that your manager made big issue because of your non-communication. This is obvious. Since you had failed to meet your deliverable, your manager's perceptions about you were different. At this stage, you should have been cautious not to damage your reputation further. However, you did not show seriousness.
d) You have written that "I have not picked up calls from office sometime". Seniors always take it seriously when juniors do not pick up their calls. If you were unable to take the call, then you should return the call at the earliest.
Lessons to be learnt: - Hope you are serious about your employment. If yes, then you need to learn following lessons:
a) Most important is you have not understood principles of communication. Your attitude is not communicative. Communication just does not mean how you speak but being proactive in passing the information. Your manager could have become upset on you even if your deliverables were good but if you had not shown communicative attitude.
b) Have you analysed why you are not able to meet the deliverable? Is it because of lack of job knowledge? What is hold up? Minor mistakes of star performers are always condoned. However, this is not in your case.
c) Your manager may lack managerial skills. Nevertheless, there is no provision to choose your manager. Therefore, it is better if you tune yourself to the management style of your manager.
d) The obvious impression from your post is that you need to improve your business writing skills. You have written your post in one single paragraph. You have used compound sentences but there is no relation between subject and predicate. Sentences are unnecessarily long. There are neither transitory words nor transitory sentences. Sooner you work on your weakness, the better.
