Problem with phone and service

<p>Im really unhappy how istore handled my iphone 6 problem. I bought it cash from them the first one and had no issue. I dropped it and the screen broke. I took out the insurance which replace the iPhone 2 times after you pay R 800 rand. I got the replacement phone which was working fine until it bombed out. The first thing they do, even if the screen is broken or whatever the send it away to their service centre. So with the second phone they came back and said it was me who created the phone to crash, but everyone in the store said it was software non the less i paid it, so here i get my last phone on the warranty. Got it struggle to get signal and after about an hour of struggling inside the shop we got signal. I just left the shop to try and make a phone call and i could not hear the person on the other side. I thought it was their phone and not mine as it is a apple and new. Just to fine out I'm wrong. I took the phone back and everyone there at the store in Brooklyn agreed there is defiantly a problem with the phone i got 1 day ago, i phone then i do not hear the other person, or i phone and i can hear the other person but he cannot hear me and when you phone the loud speaker does not get highlighted, everyone in the store including the store manager confirmed this while even using a diffrent sim. Again they went trough the process to send it back to the service centre. After +\- 6 weeks i get a message phone is ready to collect. I got there where the handed me the paper saying nothing was wrong with the phone. After i told them that this is bull and everyone here verified this the manager told me he understand but they need to send it back and there is nothing he can do. Again everyone verefied that the phone was not working. With disamay i handed the phone back. Please take note that after 12 weeks i did not have a iphone 6 which i paid for. Again it was sent back to the service center. +\- 6 weeks again get a message phone is ready for collection. Got there same story. This time it seemed phone is working. Leaving with the phone a day after i loaded all my aps and updates same thing started happening. Take it back again they say they cannot replace they have to send it back again. Everyone testing the phone indicating same issue. Now we are looking at 18 weeks where i had minimal like one day ussage. +\- 6 weeks again i get message to collect. Got there again same storrie no issue all is fine. I lost it. Have the phone in my hand not even 3 min same issue. I had to keep my cool not to break the phone. Now everyone is trying to calm me down phoning the store manager and he again comes with his **** saying k verstaan. The more i say i want i new phone the more they say they cannot they have to send it away again. But they promise me they will keep me updated and they will raise it to the highest level possible. Again i gave in my phone. I heard nothing from this store or any feedback. Just a message please come and fetch phone. So now i go hopping it is sorted. Get there same story but it seems that the phone is working. Cool no issue. The next day same **** started again. Now i go there again just to find out they have no lend phone. Now im sitting with phone that works then not works then not. Putting it on and off untill it works wasting money and missing major calls. *** never again. I want to go and break this phone and all they say sorry i have to send it again. Need help with this......
