whatsapp today seems to have connection probs, be it on wifi or mobile connection. anyone of you face it? no the right signs at all. server status is ok. weird. 

Hi, to follow up on my case, Samsung called back and said that because my warranty has void, they need to charge me RM750 to change the motherboard. Should I proceed or just take the phone back? According to them, my phone cannot even be turned on thus they can't help me. Is it true? Or they are just trying to scare me?
