Iphone Charger

I decided to buy an original IPhone charger since I've already bought an imitation which both only lasted for a month. Each cost P300. I went along with my friend at work to SM Bacoor to buy the said charger last May 24, 2012. It cost me P1800, urgh! I find it really expensive so I am expecting that this should be a good  one. Well after more than a month the end part of the charger that goes to my phone looks a little twisted. I ignored it because its still working. But yesterday it started not to work. It doesn't charge anymore. Waaaaaa! We went to Power Mac and show my receipt. The questioning of the employee there is that I did something wrong and its fault that caused the damaged. Honestly, I really cannot remember that I did something wrong with it. I am very careful in using and keeping it because I find it expensive. After few minutes the employee came back to me with a small paper with the address of their service center in Greenbelt Makati. Wow! I still need to go their for my charger to be replaced. I don't think its something repairable since its wiring in the charger that is damaged. Why don't they just give me a new data cable and then they get a replacement instead. Haayss.... so annoying. I asked my mom to accompany this coming Saturday and I am hoping that they will replace the cable. I guess it will be a "gala time" for us too. I haven't visited Makati for a while. I find it too far and I hate the traffic.
