Thanks for the help/support guys, really appreciated.
I actually did try very hard with Andrews to get a replacement and mentioned that I felt like I should have gone to the department of fair trading, however they basically responded with "well go ahead and try then" and told me they'd "see me at the hearing" (or words to that effect) which I was REALLY surprised about. They then said they would repair them on good faith, so I didn't pursue it further as I figured the repairs would be adequate...
I took a few photos just after they fell apart as I was so shocked, so I'll post them below this. The photos are of the eyecups after they split and fell away from the body, the nut attached to the tripod adapter after it ripped out of the body, and a shot of the body where the nut used to be
.
Yes, to the guy who asked if the nut's thread is now stripped, I'm guessing that's the main problem...
Also yes mike, those are the binoculars I bought, the very same.
