i'm disapointed with your uncautious doing.

I did not receive a call because my cable phone was instanly broken. However I did not know it by receiving your messenger through cell phone. I think if you know something is wrong, you need to try to call to cell phone. I knew you were absent if anything.

Hello there Sir [이름], Good evening sir and I would like to apologize for not calling you on your mobile because your telephone is not working. I called several times on your telephone and it was not ringing, since you are enrolled on a telephone class I am not allowed to call you on your mobile without any endorsement from my managers. We follow certain rules in our company and I am sorry if this caused you disappointment. I hope that tomorrow, I would be able to talk to you on your telephone. Sorry again and hope you understand. See you and have a good evening^^ Teacher May   I did not receive a call because my cable phone was instanly broken. >> I didn\'t receive any call from you because my cable phone was broken.
