Problem note solved

On Monday 15th Feb i took my Samsung Galaxy note 4 in to the shop, my phone wold not stay on unless it was on charge.<br> I left my phone with them and got 5 messages saying they where waiting for parts<br> <br> On Friday the 19th of Feb i was informed via a phone call that my phone was ready but they needed to replace the battery at a cost of R400 due to the fact it would not stay charged all day because it is faulty.<br> I asked if it was the battery that was causing the problem i was told no the problem had been resolved.<br> <br> On the Saturday went to collect my phone. <br> When i got home i tried to turn my phone on and it did the same thing as before, I put it on charge to see if i would start that way and still nothing.<br> <br> the problem was not solved they made the problem worse.<br> the phone now does not stay on at ALL<br> <br> on the job details all it says is \IMEI validation
