For the sake of transparency, Richersounds have been in touch, and going through the processes of everything.
The only thing I'm still not keen on, however, is that all they're doing is speaking to Sony on my behalf - my warranty is with RS, not Sony.
Having taken Sony to small claims previously, but settled before any hearings etc, I'm not overly keen on letting them deal with any warranty situations again
But, to be clear, I am in regular contact with a nice gentleman, who's calling me on a weekly basis to keep me updated etc - can't fault this side of stuff
Nice to have a company take notice for once, and put the effort in, even if I don't necessarily agree with their overall policy
