Not taking responsibility

I purchased my phone on the 17th of October 2015.<br> Within 3 days after purchase, the phone started switching off by itself. This happens when you put the phone down - just like that, it switches off, which means that I did not know that I missed messages and calls of importance<br> At least once a day, the phone would reset itself to the 1st of January 2013 at 12h00. <br> The screen \runs"when trying to select a contact or ringtone. <br> Contacted AG Mobile via their facebook inbox and was asked for my mail address. I supp**** my address and received a mail from Bilal who suggested that I try and take the phone back"
