Vodacom repairs and after service

I have handed in my Phone in for a repair because of the fact that my sim cards intermittently picks up and of a Pink block on the screen that shows up from time to time they said it would take 2 weeks and on the 4 July I booked it in, so I called to hear if I can hand the phone in at closer branch as i was already there while i have booked it and they say it is faster this way. I got a call from the guy working at the first branch telling me why you have gone there, he is getting a lot of trouble from the tech at other branch, I must have not done this and i said i did ask. I phoned arc a few times for the progress of the phone as the 2 weeks was getting closer, and I was given a lender an R500 Huawei phone that gave me trouble. On pick up on the 12 of July, I saw and pointed out as I was unwrapping the phone that there are bits of the plastic missing and a perfect line on the screen and bigger gaps on 2 sides of the back cover. Arc said I should not leave with the phone from the store and book it in again for 2 weeks and yet again work with the R500 as they do not issue a like-to-like phone for the meantime as this was my only phone. So, I have booked it in again and they will make it a priority. So, on the 16 July I phoned arc to check the progress and they told me that the Wable number was made on the Tuesday and when I phoned the Branche, they told me that their vehicle was in for service, and they could only take it that day. So, I was already suspicious about the situation. So, on the 25th of July I picked up the phone and everything looked good from the outside and put on a R300 plastic protection for the screen. But after t 4 days when I was what's calling my girlfriend, I saw the camera looked blurry and brushed it off as it can be what's app. But I was wrong when I saw on 6 Aug to take a photo with the normal camera app that it was the same and as well laggy. I also saw on the 3 that the screen flickers when I am out in the sunlight as I don't normally go out as I work from 7 to sometimes till 9 in the evening. So, I don't really go out. I also noticed a black half circle next to the camera and sometimes the screen does not pick up my touch. I have handed with the repairs I am not handing my phone in for repairs again. This is my only phone I have got, and I don't care for the camera but I if I need it i want to take decent photos. With regarding to the screen flickering when I get into the sun, I don't know what is going on there and also sometimes do not pick up a tap. I am not going to book the phone in a 3de time and if comes to this, this will be the end of my relationship with Vodacom. Let me know what the next step is. I have been waiting for more than a month for the dispute to take action. It seems that they are more willing to help you get a phone but after service there is non.
