How is that my problem?

<p>I took in my Cell Phone Samsung (J7 Prime) for a software update on the 15th May 2017 and i was told that i will get my phone back on Saturday or Sunday but then i couldnt make it to the store then. Monday morning i called the Store (Samsung Rosebank) to ask if they have my phone? i was told the phone is still not ready, on Tueday 23th May 2017 i called again to ask about the phone, i was told by (Thabiso) that the signed document got misplaced by the technitions and now the warehouse cant send the phone back to the store cause they do not know who the phone belongs to. HOW IS THAT MY PROBLEM? im now on the second week without a phone. I NEED MY PHONE BACK TODAY.</p>
