Anti colic bottles leaking

Hello Peter,I bought the tommee yippee anti-colic bottles for my 3months old baby. It was leaking when I used it. I laid a complaint on the Tommee Tippee messenger on Facebook and they made it seem like I’m the one who ruined the bottles . Till now they are still leaking and these bottles are expensive to be leaking. I even bought new **** thinking that’s the problem but still no difference. Can you kindly assist me by exposing them and their poor service.
