Terrible quality Sony Z3. Really Disappointed.

I bought a Sony Z3 about 4 Months ago and recently the Screen stopped working out of nowhere. I sent the phone in for repairs and they fixed it. It wasn't even a month and the phone had the same problem. The touchscreen is completely unresponsive and makes the phone useless to use. I put the phone in my drawer for a couple days till I had the time to take it back to get repaired again. When I took it out of the drawer, the phone battery has expanded and pushed the back of the phone out of the frame, making it impossible to repair because the cost is too high. After all these problems with a basically brand new Sony Z3, I am unsatisfied with their service and products. I'm going to never buy a Sony phone again, because this is ridiculous. It's been 4 months and the phone is trash and I'm left with nothing. Really bad quality product, I am very disappointed in what I got for my money.
