Thank you all for your advice. This morning I received a call from Vincent Bond, all thanks to this site, and I have had everything explained to me. I've cancelled with Creditfix, as an IVA is absolutely the wrong thing for us right now, and we're starting a DMP with a view to changing to an IVA if needed at any point.
WHat a relief. I think my instincts were right.
I really appreciate all of your advice, thank you.
Creditfix took my debit card details with a view to charging my card on the 27th, they've said this has been cancelled now but I'm cancelling my card too as I have read some horror stories.
I'm so glad this forum was here, I'll be reading it much more in future
