DO NOT trust them or send them any money. Any 'loan' company which says you can have a loan while asking you for a broker or admin fee will, more often than not, do nothing for you. A reputable loan company will never ask for a fee upfront but will instead absorb their costs into the repayments.
Send ing money to a loan company like this is no guarantee you'll actually get a loan (despite their assurances of being 'pre-approved' - no such thing!). More often than not you'll pay the fee, get fobbed off while they 'try to find a lender for you' (rubbish), and end up having to chase them for a refund of the fee which can turn into a lengthy process. It's not worth it.
