Tommee Tippee Bottle Leaking After 3 Months

I’ve been using a Tommee Tippee bottle for less than 3 months, and it has suddenly started leaking excessively. Is this a joke? I spent a lot of money on this, and now I’m expected to buy a new one? I’ve always loved this brand, but now it feels like a complete waste. I’m really disappointed and need this issue resolved immediately. This isn’t the quality I expect from Tommee Tippee. Please assist me as soon as possible!
