UNHAPPY VODACOM CUSTOMER

I am a customer of Vodacom since 2003. I upgrade my phone - Samsung S4 to a Samsung S6 Edge on 01/09/2015.Since day one I had problems with the Samsung S6 Edge. It is now 5times in 7 months that my phone went in for repairs. If you calculate (It takes normally 3-4 weeks - if you are lucky) for a repair.Make the sum: 5 times in for a repair, multiply it by 3weeks= 15 weeks, that add ups tot plus minus 3 months!! I need to pay for something I don`t have! Between Middelburg, Emalahleni and ARC - NOBODY wants to help me! Every time you speak to somebody the only answer that you get is \We going to see what we can do\". Today I phoned ARC Menlyn to confirm if they did received my phone, they told me the don`t have the phone, it is in Emalahleni for 3 days doing nothing, and that is after they told me that they are going to send it to ARC because THEY will be able to assist me! It is unacceptable! I want an answer before the end of Friday (22/04/2016) or I will have to take the matter further. The dates and Job numbers what my phone was send in for repairs is: 08/01/2016 - ***8, 03/02/2016 - ***6, 04/03/2016 - ***4, 31/08/2016 - ***9 and 12/04/2016 - ***7"
