Phone Repairs 5 time and still not fixed

I have a Samsung Note 3 phone. It's been in for repairs 4 times and every time the phone comes back with another issue. I have taken it to the Smart Center in Roodepoort and I speak to Tirone every time. Clearly he can't sort out the issue on the phone. I have asked him that i want to speak to his manager and every time i get told that his manager is not in.<br> <br> They have replaced the charging board, and the I got it back. It still didn't charge. They they have replayed the Main board. That sorted the charging. But then the Camera didn't work. Took it back and i was told that it was the NEW main board that they have installed that was an issue. They again replaced the main board and still didn't work.<br> <br> Took it back again and then i was told to wait. After 45 min he came out and told me that there are no faults. Took the phone and leave. and the problem is still there. <br> <br> Now i have to go back to them and book it in for the 5th time to get it sorted. Where do you draw the line on this and how many times does this phone have to go back for repairs?<br> <br> I think it's time that they face the fact that they cant fix it and they need to replace it with a new one
