Refusing the bottle. The formula milk?

Hi, my daughter is 3 months old and has been on breast milk (not exclusively). Lately, my lactation has come down drastically even with the help of lactare tablets ( which I'm taking 6 per day). My baby's weight gain has also been affected due to this and my pediatrician has asked me to give her top feed twice a day (90ml each time). I've bought a tin of lactogen and every time I try to bottle feed her, she brings the roof down. She hates to be fed by bottle or palada or spoon or dropper or anything else I've tried. She cries herself to sleep but won't drink the formula milk. I'm worried about my baby's health. Is there any specific feeding bottle that she might like or should I change the formula milk? Please help. Thanks in advance.
