I received a call from D&G, with whom I used to have a (free) warranty extension, which is about to expire.
They called me by my correct name. I was then asked to quote my address, to which I asked them to tell me what they thought it was, as it was them that had called me. But they "could not give that information out over the 'phone, due to privacy concerns". So it's ok and safe if I tell them, who could be anybody, but they can't tell me what they believe my address to be. If it was in fact D&G.
We live in a strange world.
