Bests & Worsts Reviews from Amazon

Just received the Iphone 5C blue - it worked for the 1st 2 days, then it started to turn off by itself (even though its fully charged and won't turn on after a certain time period). I tried to do hard reset and even did a full system restore - and still the problem persists... I just contacted the seller, but so far, haven't heard from the seller yet..... Funny how when I placed the order they very quickly process and charge the order, but when there's a problem it takes a while for them to respond.!!!
