I know this is a first world problem, but I'm so upset over this.
I've been extremely strapped for money recently, and in general I'm not a big spender.
But I decided to treat myself to something nice after a particularly rough week. (Work, bf everything was rubbish)
I bought a lipstick which in my opinion is expensive (£25) - I'd been eyeing this for weeks!!
It turns out that the lipstick is horrible.
It actually dries my lips out and doesn't stay for longer than 5 mins. It's practically the worst lipstick I've ever used.
I did go back in store to complain about this but they refused to help me 
I know a lot people will think I'm making a mountain out of a molehill, but money is tight for me and I'd treated myself to something nice after a very long time.
I'm soooo disappointed that the brand won't take any responsibility for the horrible product they've churned out.
Anyway, rant over.
Clearly a first world problem, but I hate wasting money
