Sent Samsung an email around 9am this morning, and the customer service person called me back at 1pm.
Conclusion is... They are going to exchange a new handset for me.
I have to surrender my current phone though. Another catch is... I have to wait for two to three weeks.
Feels like I won a battle, but it seems too early to celebrate for now.
Also attempted to utilize my phone today, but it restarted itself close to 10 times from 9am to 11pm so far.
One last point to add - Although I'm really angry, but I genuinely appreciate the fact that they replied despite the fact that it's Sunday.
