1. The president is a JOKE.So, I will not be returning to the Philippines. Again, this might be irrational, but I expect a more generous response, even if it would have been a token refund. That two independent businesses did the same thing tells me this is not a place that deserves my money. I have been in Asia many times, and I think this kind of thing is not the norm (except in Vietnam).
Sorry for sounding bitter.
2. Unless diving at peak seasons(Easter and Christmas) and using private transfer,advanced payment is really un-necessary in this country.
3. Desert another chance.
4. You have every right to be bitter!
5. If you ever change your opinion on the country and thinking a trip to PG. This is my suggestion:
a. Book a room in Ermita in Manila through eg Agoda or similar which offer FREE cancellation.
b. Use the Si-kat transfer(City State Tower Hotel) in the following morning.
c. ditto for the return.
