Inner chainring bent on 6 week old MTB I bought a new Voodoo Bizango 2015 6 weeks ago. When I was out earlier I changed down and the chain somehow got wedged between the 2 front chainrings (It's 2x10) and bent the inner ring. I've read on here that this just shouldn't happen unless the chainring was a bit dodgy. 

Do you folks think Halfords will cover the part or should I just bite the bullet and get a new chainset? I went into Halfords earlier but have to book the bike in for next week....i'm not very patient :)

Alternatively, I've been trying to find a replacement chainring. How compatible are these? The chainset is SR Suntour CW-XCM-D 22/36T. I'd prefer to go this route so I can buy a couple of them in case it happens again. I can't find the Suntour chainring but there's plenty of Shimano 22T 64BCD online, I'm just not 100% if they will be correct for the bike.

Here's the badness
This could have also been a loose mounting bolt causing the excessive gap.  So here's the way warranty works.  The bike shop looks at your bike.  They make a recommendation to the manufacturer about what caused the defect.  If they believe it was


loose bolts on the small sprocket from the factory
slightly bent sprocket from the factory, made worse by the chain falling off 
wrong chain used for the application (8,9,10 + sprocket chain width)


and they manufacturer says yes, they will re-imburse your local bike shop for the repair then you have a winner.  In some cases the manufacturer says no, they didn't cause that defect.  In that case the bike shop could build goodwill with you by repairing it at their cost to keep you as a happy customer. Talk to your bike shop.  DONT touch the area with tools at all (let the bike shop to that as part of fault assessment...)  Work with your bike shop to come to a resolve that makes everyone happy.  

If that fails, and the bike shop says sorry, you are out of luck in obtaining a free repair there are always other options.  If you are a do it yourself person, you could remove the right side crank, remove the small sprocket, and bend it flat again (if its steel).  If its aluminum, toss it and get a new sprocket.  They really don't cost very much.
