Wasted time and Frustration

After being without a phone between December and January, to have the device repaired under warrantee, for over three weeks, the phone is worse than ever. The phone was barely a year old when it started giving problems, instead of replacing it they sent it away to Fourways for some reason for weeks on end and after numerous attempts, I finally got it back, only to find it was worse than ever. I lost all my data, contacts, pictures etc! I cannot afford to be without a phone again and it seems their strategy is to make it as unbearable a process as possible, to save money? Not to have to replace the phone? I've had to buy a new battery, which does not last a day, the phone freezes, reboots, is completely unreliable, but I'm too afraid to send it in again, imagine what they would do this time?
