Numbers fading

My 2 month old Advance Comfort bottles dont have writing on it anymore!! I use the tommee tippee microwave steriliser, the tt breast shields and I have a tt breastpump!! I really dont want to change brands but by the look if it I will have to!! My baby is only 4 months and I have to buy new bottles already!!! Not as if tt is the cheapest on the market... What a fool I was, to think that tt is worth the money and a good product!! Thats not fair!! I did send an email but NO reply
