Repair phones not repaired

<p>I Abrahams Coetzee upgraded my two phones in 2015. They worked perfectly from the beginning about 3 months ago they started giving problems. The phones would switch off while you were still using them, even though the battery life were still almost full. Couldn't make or receive phone calls, battery kept on draining very fast even if all apps were closed and phone was locked not doing anything. Contacts kept on dissapearing and phone freezes from time to time, cant use the screen to go back.</p> <p> </p> <p>These phones has been sent in 5 times in that 3 months and every time they say its right but it keeps on doing the same</p> <p> </p> <p>Cell C said they have changed the motherboard numerous times and also upgraded the software. Its cost us about R1500 from my own pocket for taking the phones in for repairs in Port Elizabeth, I live in Uitenhage.</p> <p> </p> <p>I feel they should have replaced the phones because I have been paying for these two phones for the last 3 month and unable to use them as I dont have an extra phone.</p> <p> </p> <p>This is the worst service I have ever had.</p> <p> </p> <p>Please assist in this matter ASAP we need working phones!!!</p>
