That's right, even Apple, on their side, confirm they can see I handed the package to Royal Mail.
And that's why I'm so frustrated, because I don't understand how this whole situation is possible, especially coming from Apple.
I asked the Customer Service to, at least, tell me what motivated their decision not to replace my phone but they don't have the information. And when I ask for a contact they tell me there's no contact I can liaise with.
Sorry to hear that, it appears, you are getting the run around from Apple. If it were me, at this point, I would send a detailed e-mail to Tim Cook, explaining what has transpired.
In my experience, in the 20 years of dealing with Apple they have always been very helpful and have always strived to do the right thing for me. What you are going through is not right. Apple needs to step up and rectify this situation.
