Bad Service

I bought Samsung Galaxy Note edge on 08/03/2015 from Clearwater Mall. It costed me R14000.00 which I paid in cash. On the 11/07/2015 I took it in for cracked screen repair and it was working and to my surprise I got a call on the 20/07/2015 from Samsung Care Centre telling me that I need to pay R3,800.00 as the phone was not working. <br> <br> May you please assist on this issue as I've been sent from pillar to post with no success. I want a new phone as I used this phone for only 4 months. This is really unfair as I was under impression that Samsung has best product. Please contact me ASAP as I don't have a phone at the moment. Samsung really dissapointed me and I will never recommend anyone to buy this product.<br>
