Not suggesting anyone here is doing this but it is happening as was a few people joining it with the sole reason of convering expensive pre existing conditions
Well that is what they were selling on their fancy hotel presentations and they should stay behind their side of the deal up to a maximum limit (5 mil USD, pre existing cover ) Also they were very vocal how they don't care if you go straight to them for claims and not even talk to EK. From the increased premiums looks that they are realizing that people who bought their health card actually want to use it. Baymac's reaction is typical for this place and unregulated markets where you have no legal protection.
As always, a few spoil it for the rest
I am sure those people became sick just so they can spoil the fun of the healthy bunch. So rude!
