No love for the love bracelet

Collected my yellow gold bracelet at Cartier today. Since buying it a few years ago it's come off my wrist completely twice. First time just six months after buying it. Handed it in for repair and was reassured it would never happen again. 18 months after that, it happened again!! Absolutely shocking but luckily I found both pieces. My white gold bracelet that is much older than the yellow gold has been sitting on my wrist the whole time with the exception for when I had a spray tan done. And I barely have to tighten its screws. Honestly thought they would offer me a brand new one this time. Instead they had the cheek to ask me if I wanted the polishing service for £100! Disappointing to say the least!
