Baby is not eating formula

Girls please help with advice! My 8 months old baby is rejecting all types of formula. She was breastfeeding only but before 3 months old used to have 1 bottle of formula. After 3 months she is not eating from bottle. Even if my milk inside she is fighting to take away. I have tried different nipples and water bottle. She is asking my milk from breast. But my milk is not enough. First tooth grew 10 days back. Solids she is having 3 times in a day with crying. Hating baby oats. Need to transfer her to formula food only and don’t know what to do!
