Terrible Quality- Stay Away

I got Tommee Tippee products as gifts for my baby because that's what I wanted. As a first time mom I wanted the best for my baby so I started using Tommee Tippee bottles the moment we brought my baby home but they started fading from as early as four weeks, I was so disappointed that I changed to a different brand when my son was 7 weeks old. I wrote to Tommee Tippee about this issue but they are blaming it on the sterilizer, they even said that my bottles were out of warranty but I know they were all bought by my colleagues in July 2019. Their company totally refuses to take responsibility and this is frustrating considering the price of these items. I even complained about their manual breast pump that did not work at all and they want a receipt even though I explained that it was a gift. I am defeated. I would not recommend this product to anyone.
