I am sorry, because time does not match, I can not find you in time for you to come I work from Monday - Saturday Sunday is my day off work. I hope you understand me.
I apologize because our available time mismatch, I rarely meet with you at the time you called I work from Monday-Saturday, Sunday is a holiday for my work. I hope you will understand me.
I'm sorry we do not match, because it's free, so I don't see you at the time that you called, and I work from Monday - Saturday, Sunday is my day to strike. I hope that you will understand me
