*********** staff at repair center

I've been a Vodacom contract customer for over 10 years. The recent service I've had with their head office repair center is nothing less than useless. My Samsung Note 4 LTE was booked in on the 12/08/2015 job number *** for the phone losing signal and going blank the phone was fixed for a about a month and started doing the same thing. I took it back to Vodacom repair Eastgate on the 28/10/2015 job number *** where they were very helpful and rebooked the phone in again for the same faults and more. Eastgate repair center couldn't fix it and sent it to their head office repair center ***. On 03/11/2015 job number *** for losing signal, screen going blank, no service error, not charging and a camera fault. I called Vodacom Eastgate and was told they should receive my phone back on the 05/11/2015. So the 5th came no response from the head office on the where about on my phone. On the 09/11/2015 I called *** and was told my phone is on route to Vodacom Eastgate they will receive it on the 10/11/2015, so I said fine and asked what was wrong with the phone and was told they did a software upgrade which was done on the previous repair.
