BlackBerry 8520 — defective unit

to whom this may concern;

i have sent my black berry phone for repair via globe telecom to blackberry repair service in singapore they made me wait for 3 months when they returned my unit it is still the same never repaired i complained at globe telecom philippines but they asked me to return the unit agian and they will return to singapore repair shop again meaning i need to wait for another 3 months again what the hell are those repair shops of blackberry is doing out there ? staring at the phone waiting for it to repair itself ? i was not born yesterday and i perfectly know that if you open the unit of any cellphone and try to repair it automatically the software will be reset and all the data that you have stored will be lost , but when they returned my unit nothing has changed including the text messages that i had since december is still intact , blackberry why are you paying people doing nothing but destroying your name ? maybe you want to address to problems like this
