Philippine call center - look up curse words in Tagalog, and you'll quickly be able to see they want to get off the phone quickly.
Philippine culture does not like Americans cursing at them, and they show their emotions easily.
With that being said, this time share scam is all about "lowering your maintenance fees". I am supposed to be called back by a "Mr. Lee at 888 772 0122".
The scam is that you have to pay them first, in order to get really low maintenance fees on the time share. This of course will never happen and they'll simply take your money and run.
