Faulty smart device

I ordered a smart device on the 28 Aug and on the 31 Aug device delivered and my account billed for delivery happiness there. Since Tuesday when I woke up the phone would be switched off and when I power on the phone there enough battery. I even reset the phone but the problem persists. On Friday 4 Sep I logged a querry with FNB ticket number \FNB***F". And they advised that between 24 and 48 hours I will get a call for my replacement device delivery. On Sunday when I woke up the phone was off as usual and this time it wouldnt power on completely all it does is show the sony xperria splash and restarts. I dont have a phone and the agent I keep on getting when I call the call centre doesnt even know when the replacement. approval will be done if it will be approved.<br> You were quick to delivery a non functional phone and too slow to get it replaced. Whats the point of saying if the device is faulty you will have it replaced if its within 7 days.<br> <br> FNB Smart device centre ***<br> IMEI: ***<br> Call ***<br> Call ended: 10:07AM<br> Called again 07 Sept 2015<br> Called again @12:42 08 Sept<br> call centre agent \""aka device guru\"" Ravia<br> """
