Thanks to Antony. He is the best. I had issues with my baby bottles with a ton of questions. Antony was professional and very patient with me. He listened to my concerns one by one. He was very knowledgeable and able to resolve all of my issues. Tommee Tippee is the best and further more customer service is excellent. Thank you Antony and to Tommee Tippee as the Advanced Anti-Collic bottles saved my babies life.
