hello s and welcome to the forum. I am not an IVA expert, but at one time I was looking into one. I had a repayment mortgage and would have switched to an interest only to afford the IVA. My IVA was unrealistic so the repayment mortgage remained. I think it's standard procedure for an IP to suggest switching to an interest only mortgage only to free up some much needed funds which can be applied to your IVA. I hoped this helped you somewhat.
As for DebtFree not contacting you continue to email, rang and send recorded post if needed until they do conatct you. Also, try contacting the IP directly who drew up your IVA proposal.Although DebtFree is an IVA mill someone, an individual has to be managing your case.
And no it's not 'normal' for you to be ignored, but some people do get fuffed around and that's just plain rude. Yes, they are busy, but you are a client and deserve better treatment.
As for the creditor threatening court action. You've done your bit by sending them notification of your IVA. The creditor can contact your IP.
Someone will be along shortly who is an expert and can help you further.
Take care.
All I have left is my humour.
