COPY OF PROOF OF PURCHASE
I have a problem with a secondhand devise I bought from someone. I have been using the devise for more than a month now and my service provider says there has been an online blacklisting request for the phone. the phone is using my apple id and face recognition and everything is working well. 13 August I started getting network problems and now I am told that to sort out the matter I need to submit proof of purchse for the phone. Now i can't get hold of the seller. What I don't understand the are questions that are asked before a blacklisting is done, and no one seem to know who did the blacklisting and why. Is there a way I can gethelp with regard to the unblacklisting. I have submitted an affidavit, copy of my id and filled in an unblacklisting form. all these docs are with my service provider, now they want proof of purchase and I can't access that information in istore. apple have all my details/ credentials and i am a long time apple user.
