I Can’t Find Replacement Parts for My Munchkin Bottle

I bought a Munchkin bottle because I was promised quality and easy access to replacement parts. Unfortunately, the straw broke and has yellowed, but I can’t find any spare parts anywhere. I switched from Philips Avent to Munchkin specifically because I was told parts would be available. I’ve called and emailed multiple times, but there’s no one to help—just an email address with no response. This lack of support is frustrating, especially for a brand that claims to be reliable. I’m asking Munchkin to provide proper assistance and make replacement parts accessible so I can continue using the product without hassle.
