Worst infant nursing bottles

To whom it may concern

I'm completely dissatisfied with your baby feeding bottles that I purchased. Both the bottles won't fully close at the bottom of the bottle,the milk spilled out of the bottle landing on my daughter almost causing a serious danger to her. I'm so unhappy and dissatisfied. Was this bottle design tested before it went out to stores for sale??? My daughter could've choked from the milk that poured out the bottle. I'm really taking this matter seriously. I have pictures of the bottle and how does one get in contact with your brand
