New to IVA. Help please.

DH and I have recently signed into an IVA and are hugely relieved.

My question is. I had a 'detachment of earnings' which takes a percentage of my wage each month via my employer.

I've had 2 wages since the IVA began which have still taken money from my wage. Does anyone know if these deductions will be reimbursed or taken off my final debt please?

I'm hoping for the former as the IVA was calculated on my wage with the deduction and we'll struggle if we pay it again this month. It definitely included in the IVA and is therefore 'written off'.

TIA
