If you put these names into search the site at the bottom of topics you will find what others think. Re advantage loans AB removed their adverts from this site.
They are real, but not particularly good. They most likely charge a fee for set up that is unlikely to get refunded. I have posted numerous times on this issue already, if you are interested have a search as oldwoman says.
They are brokers who will charge you to find a loan. The problem is that the fact you are going down this route means that your credit is likely to be blemished, therefore they will be unsuccessful in finding you a loan but they will keep the "fee" as they will have tried. Do not touch with a barge pole. They are not frauds as such merely unscrupulous as they take advantage (!) of people who have nad credit.
