BAD SERVICE DELIVERY

I will NEVER purchase any samsung product EVER AGAIN!!!! I got a new phone last year October and in January i had difficulty charging the phone as there seemed to be in issue with the charging port. So i took my phone to the Samsung Service Centre in Menlyn and what a big MISTAKE this was!! My phone was (still under warranty) given in on the 26th of January 2018. After numerous calls and visits ( whilst living in Centurion) my phone was only given back to me a few days ago damaged, and with missing part/s which the service consultant did not inform me that i should keep before handing in my phone, thus resulting me in booking it in again so they can resolve the issue,,., My new phone was now visibly a second hand phone due to damages from the service centre ... Speaking to the manager who promised me that this all will be sorted out ASAP, Today i am still left without my phone - 09/04/2018. All promise to call me back etc. but still NO FEEDBACK!! This is always the issue, they are quick to sell you the products and the greatness thereof but when it comes to customer service, well it seems they" will be back in 5 minutes" or rater a few months later..... what big frustration this has been!!! Absolutely very BAD SERVICE DELIVERY
