Refusing bottle after returning to work

Sharon
Hey working moms , my 4 month old fights the bottle when I'm away at work . She took 5 ounces the 10 hours I was away ! :(
My best friend suggested to pump exclusively since she had to, but I really enjoy breastfeeding her when I am at home . 
Anyone have the same issue ? and if so did your baby eventually take both the bottle and breast or did you have to resort to exclusive bottle feeding ? Thanks !!!
