You need to seek a full review of your income and expenditure and if there is no sign of gaining new employment then possibly seek a full and final offer on payments made to date to end the iva early.
Sharing from experiences of dealing with debt
There is a solution for everyone .... Just need to stay positive !
Good advice from Luluj -- but, in the meantime, request a payment break from your IP while you sort this out, as three missed payments without agreement will fail the IVA.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
