I recently ordered a magnetic dry-wipe whiteboard on Amazon, and when installing it, I noticed there is a distinct crease/ripple in the board. I payed £40 for this so I've requested a refund, but as expected the seller is being rather unhelpful in getting back to me (it's been 4 days and they're not supposed to take more than 2). Is there any way I can flatten out a crease in a magnetic whiteboard? Thanks. via /r/DIY http://bit.ly/2IrNLdp
