Samsung - bad service and DO NOT ANSWER THE PHONE

Taken my phone back to Samsung Constantia Office Park again as the orignal fault was not fixed. Still no news from them since 19 September 2015. All phone lines to the call centre are either constantly engaged or never get answered....I have managed to get through twice and both times I was told someone would get back to me...I'm still waiting. Appalling service. Just FYI, when visiting the store at Constantia office park its concerning that many of their display shelves are empty of the products they are suppose to be selling. Not a good impression at all...
