I did it all by phone much prefer it rather than email. Any progress on your case ??

Yes, they now want to organise a collection of the faulty headset FFS. Thinking that I should just tell them that I disposed of it to avoid a house fire or for safety reasons or something. They will probably end the case and refuse a refund, but I can't see what else to do.

Email the courier asking whether or not it is safe to post this item. If it's a leaking battery its classified as a hazardous material by UPS who Im guessing is the courier.  Call them to ask whether it's safe to post it say how its classified as a hazardous material and ask like your double checking and playing it safe you don't want to get in trouble. Mention how the Royale mail refused to post this item. Ask ups or whoever it is for Email confirmation they won't accept this parcel and pass that on to sony.

Yep, that is what I had planned to do, but unless they have mistyped (which is possible) THEY want to organise a courier to collect it from my doorstep. I don't know what courier they will use and it could even be some special one that could transport those materials. I will look for a law forbidding it, and that would be concrete.
