It would be at the Central Bangna on Dec 23, 2015 between 13:00-16:00. You may ask your messenger to call me at, 098-552-2267, when he arrives at the Central Bangna.
If I change my mind later to return the device at the airport instead, would it be possible? Do I need to call or do anything in advance?
Do I need to call to confirm my order again before picking up the device?
