I went through this a few weeks ago. Had a replacement within the week but the customer service quirk was if I chased up by email, I was told my request would go to the bottom of the pile.
They're collecting it Friday and replacement is supposed to ship as soon as mine is in transit to them.
Anyone who says my request goes to the bottom of the pile will quickly find themselves inundated with tickets. They will think it's a bot but it'll just be me replacing miles with messages.
I tried to fix mine myself by taking the whole thing apart to bang a locking key in...it helped reduce the volume of the issue but the whole unit still needed replacing.
It's a shame, the actual unit was great till it wasn't.
