Put on a nice dress with lipstick and talk to him nicely make
sure you find out what hair colour girls he like so you can dye
your wig.......
Just tell him you want to stop the lessons la then ask him about
refund.......tell him you want to forfit the 1st 15 lesson de
payment, sounds fair since u go for 12 lessons liao remaining 3 you
forfit.
That way he cant make excuse about rejecting other clients and
loss of income etc etc because of you..
Then the remaining 15 lessons you ask for the refund la...
If he ask why just say you are going overseas for some job la or
you just simply tell him what you feel about him...who knows out of
desperation he might change his attitude..
