Happened to me the vets kept teling me it would take 8-10 weeks and I shouldn't panic but I rang the BVA and they said they were processing plates that were only 2 weeks old and hadn't received anything from my vets in 14 months! (slightly annoyed as when I asked if they did them regularly they said the orthopedic vet did them there all the time - clearly not!)
I rang back my vets and explained to them - they assured me they were posted and said as they weren't digital plates (apparently not many vets use digital x rays yet) they would have to be repeated and we'd only have to pay for the GA! After giving them my opinion on their idea of giving my poor girl another un-neccessary GA due to their incompetance they told me to hold out and see if they turned up. Funnily enough 4 days later the BVA rang me and said they had just arrived with a post mark of 2 days previously so couldn't have been sent months ago.
The vets must have had the plates tracked when posting so I would keep on at them and chase them up. Sorry I really hope they re-surface as particularly if it involves a GA it can be very difficult to re-do them
