I have, and as I said in another thread, gratuity received in 8 working days from last day. I asked the same question of JPAC/pensions and received the we neither confirm nor deny receiving your AFPAA1. Frustrating bearing in mind it would have been just as easy to say, yeah we got the form!! As timely receipt of gratuity and pension (whether you have or have not got a job) is one of the most important things on leaving the service, some acknowledgement is in my view essential. So those of you monitoring this thread - please consider doing something about it.
