Bad Nokia service centre experience

Gosh. I wonder why gadgets today are so vulnerable. It spoils so easily. Lolz. Yesterday was my third trip down to Nokia care centre at Wheelock's place for repair. My Nokia N73 ME phone is giving me connection error problems. I am unable to call out to other people. This is really fustrating cos when u want to call out and this problem surface. So irritating... Anyway I actually called out their hotline but they say they can only emphasis on the matter. They seem to be pushing the blame internally and i seem to be the person to lose out on it. Haizzz.... Actually i was hoping they will change a new phone for me la. Lets just hope it will come true. LOL
