I'll be honest chaps, I was offered this opportunity, but then the manufacturer instructed publicly when asked about others rattling, that it was not an issue. I lost trust at this point and thought I would just take it as a lesson learnt. I didn't want to cause a situation. To be fair it still shaves, just not as well as it did before. As you rightly say it is defective and although fit for purpose, it shouldn't deteriorate within such a short period of time (never dropped or mishandled). Anyway I have very kindly been offered a possible solution by a kind member on ATG. Really appreciative of the community we have here.
