Dishonest, False Advertising etc,etc

It’s the worst. I’ve purchased Georgini Sweetheart Bow Necklace Gold - and it tarnished. On the website prior to me purchasing this I read that it is coated and thus it’s guaranteed against tarnishing. I’ve contacted the call centre via email and sent them proof of the purchase and also their promise which is clearly advertised on their products. I received emails that said they don’t cover this … this is downright False advertising and mind you it’s on their website for this necklace also. If it wasn’t guaranteed to be against tarnishing, I wouldn’t have paid so much for it. This is so wrong … clearly Bella Luna is a downright Wripoff company. I’ve saved my hard earned money to be ****** by them.
