Problems with phalaenopsis orchid - Yellow leaves and blooms dying

[KrystalGem]

I called the florist this morning, they offered me another orchid but I declined so they gave me a store credit for the value, I'm not too keen on another overpriced orchid potted in moss! They sell homeware and gardening equipment so I'll use the credit on something that isn't going to drop dead on me!!

Stefpix the 'before' photo I posted was taken in the evening, the area it was in is brightly lit all day.

I'm going to look at orchids today, there are a few highly recommended stores nearby so I'm going to see what they have to offer/how they're potted.

Thank you everyone for the advice. One positive is this was a learning experience and there is so much helpful info on this forum, so I can start with a fresh orchid and be a little less clueless!!
