Dear Sir or Madam,
I am writing this letter to inform you that I need to cancel my booked a part-time course that I had list since three days ago.
Initially, I booked a part-time course about how to good public speaking with English language, which provide to study with lecturer at the college. In addition, I will get a certificate aimed to attach files to apply for a job.
Unfortunately, I think I will not be able to join it because I am required to take an internship to learn science and knowledge and complete my college assignment. On the other hand, I am close to writing my thesis. As a result, I will start the preparation from now.
Finally, my friend advised me to learn public speaking by joining with communication group. This is many people to join it to learn together and flexible time. As a result, I can manage my time to study it.
I hope you can receiving my response. Thank you.
Yours sincerely,
Jack
