Samsung - Note 4 , no parts and bad communication!

I booked my Note 4 in at the Samsung Service Centre Roodepoort on the 12th October 2015, collected it the next day, same symptoms took it back the 21st October 2015, they fixed it , same problems and had to book it in again on the 22nd October 2015 (Job SS*****9). Was then told that it's a software problem and the technicians would sort it out overnight. Waited for notification to collect as promised but I received no SMS, tried to call the Service Centre line it either rings or it's engaged! I have tried 9 other numbers , no answer ,via Twitter was contacted by a young lady from head office that tried to help but problem lies with the lack of communication from the Samsung Service Centre's.<br> The Service Centre sent a message saying:-\The device seem to have a hardware failure. We have placed an order for the main board."So now it's a hardware failure after \""repairing\"" the phone on two previous occasions. As a long time Samsung fan this lack of service has left a bad taste in my mouth. This phone is 6 months old and they don't have parts for it? I have now been without a phone for 20 days with no communication on a possible date of return?It's time to swop to another brand..."""
