BAD manufacturing

I purchased the tommee tippee advance colic bottles these bottles leak excessively I contacted tommee tippee about the issue and their response was an email things I could be doing wrong that's making the bottle to leak, I then purchased the closer to nature bottles and these bottles are also so problematic the whole teat gets sucked in whilst my baby is drinking, AGAIN I CONTACTED TOMMEE TIPPEE, their response was a list of things my baby is doing wrong, Alecia van Der nest who I assume is the customer care consult this woman just your time she is of NO Help.
