Looks like patience and persistence is really key to solving the issue. After several calls to the Customer Service Hotline (200) while enduring the unusually long hold times, and three trips to a Sun Shop, all is well so far. I would also like to say thank you to the customer service representative who clarified, escalated, and actively assisted me with the issue. It goes to show that if you’re patient, kind and persistent, you will get something favorable your way. Of course, there will be times where agression will be necessary but we might as well try to keep it to a minimum. Remember, there will be times when customer service representatives are powerless to help even when they are very willing.
In short, I made one final trip to the Sun Shop and one more call to the Customer Service Hotline, my mobile internet service is now working. Big thanks to the people who helped and put up with me.
