I was a former senior level employee for Oratel for some time. I came from a legitimate call centre environment and was deceived by their deluxe office and media literature. I soon found out they were a scam. Aside from being a racist, sexist, outdated management group (with few exceptions, they consistently failed to satisfy their customers (all of whom paid in advance).
Their main gimick is lead generation for the mortgage industry and even when I was there, they were constantly getting complaints form unsatisfied customers.
You may not want to publish this piece of information, but here's something you may not know: Their president, Catherine Angelatou, is the sister of one of your site's better known criminals--Pavlos Angelatos. In fact, Oratel has been pretty much empty since it opened. If that's not proof that they are front for laundering money from his directory scams, I don't know what is! What's even worse, Pavlos' poor sister is to naive to realize that she's been left holding the bag. That guy is pure evil. It's no wonder he fled the country.
