The MUA dropped me a SMS saying she will not be able to help my mother and sister do make up and hair styling on 12-Dec.

If I didn't send her a sms asking her what time she will be come over, I don't think she will inform me she has just accepted a new assignment.

Why is she so irresponsible?

Partly is my fault also, cause I didn't inform the timing on 12-Dec, but I already told her I want her to do make up for my mother and sister. I think it is a basic courtesy to inform your client 1st before you accept another assignment.

I am so disappointed with her service!
