They have a terrible reputation for charging arrangement fees for a loan and then taking months to come to a decision (uncontactable in the mean time) and then declining application and keeping the fee.
There is a topic about them on www.grumbletext.co.uk - have a look.
I have just received a mail from 'WentworthLoanApprovals' with the title: 'we have your unsecured loan approvals available'.
I have never applied for a loan and I don't know where they got my email address from.
Seems really fishy... I hope somebody hasn't stolen my identity to apply for a loan...
