My DP bought me a pair of GHDs for Christmas, I've used them a handful of times for 10 mins and today they have broke! To say I'm fuming is an understatement, they haven't even lasted a month!
Luckily there is a 12 month warranty and I can send them to be repaired, but now I have no faith in them and don't believe they're going to last very long! 
I want a refund and want to buy a different brand but I know I'm not entitled to one 
If they brake again after being repaired can I demand a refund and claim they're not fit for purpose?
