So, the two weeks are over, and as I have not received anything, I decided to try my luck with calling 01204 203802 (program code 41795) again. This time around, I managed to get through at once, and a helpful gentleman checked my name, found my documents, and told me that the queue was so long that my cashback would be delayed by another 4-6 weeks.
So, if anyone else comes across this thread looking for missing Sony 2014 cashback, do not hold your breath---we should consider ourselves lucky if we get it before Christmas!
