Horrible Service from repair center

Absolutely horrible service... I had booked my 7 month old iPhone 6 in for repairs as the screen had an issue(Lines in screen and freezing/typing by itself). Starting off with the horrible unhelpful service from Vodacom Midlands Mall customer care (think his name was Andile), he was unhelpful and mumbled throughout when answering my queries. <br> Then my phone was sent to DBN repair center, thereafter just under a week later I get a message that my phone is on its way back to PMB. So I call the care center and speak to Revasha Jumna and she stated the phone was sent back to PMB, so I said great the phone is fixed. They informed me the phone was sent back without being repaired as there was no fault found!!! So I was upset at this point so I sent her pictures of my phone with the fault, which clearly shows there is a problem!! I even asked the technician to call me, but nothing. She responded by saying the phone will be sent to JHB, I said so how long and she says until the problem comes up again???? So if it takes a year I will be without a phone??<br> I would like answers regarding the progress of my phone as I am getting no response from Vodacom Repairs DBN!!! Job Number ***4
