Yes, this actually happened today. I decided to go ahead and just purchase more of the Avent bottles that we have been using for Brandon instead of switching it up to a different brand. We have been using both Avent and Medela but I needed some more 9 oz. bottles since the smaller Medela bottles don't hold enough formula for a single feeding anymore.
So....bought the Avent bottles, a five pack of them, brought them home and went ahead and started sterilizing them. Well, below is what happened to two...they started melting in the water. Uh...pretty sure that isn't supposed to happen. I know this was a random product issue because the other 3 bottles were fine and the other bottles I purchased before never did this.
So, what do I do? Call the manufacturer and ask for replacements. Yep, the agreed. I will be receiving two new bottles with 5-7 business days.
It was so nice, for once, to have an issue with a product, call the manufacturer, actually get to a person within 2 minutes, and have the problem totally resolved within about 5. High praise to there customer service team.
