Yes I find it unbelievable that OCUK is 100% flat-out refusing to consider anything other than it did not happen before I received it.
I understand it's very unlikely to be the courier's fault
the terms and conditions issued to you in the RMA confirmation explain this clearly. I have quoted below for reference.
we are simply unable to support damaged products.
the product could only have been damaged after a term of use, in your possession.
I really would like to avoid this becoming a public matter, however it does seem that you hold responsibility for customer induced damage on this occasion.
