I’m from Australia and haven’t heard either, though it may be because I also have no dedicated SA as I prefer to buy online. I have 2 SCs, cobalt & cherry from 2012 and 2013, respectively who are both pristine. There’s no way that I’d give them up for a refund. I will keep using them on rotation & enjoy them until they start showing whatever defects they are meant to have. If and when that time comes, I’ll just chuck it up to wear & tear.
