ccj for £120 a month now notice of issue of warrant of control hoist portfolio holdin

[okis]

Hi wonder if anybody can help me please i had a ccj from these people to which i didnt respond and the judgement was made for £120 a month to which i cannot afford to be honest i buried my head but now they have sent me a notice of issue of warrant control. I have until the 4th april I was going to ring the bailiff and offer him the £50 i was going to pay for the variation order instead of paying it to the court I just wondered if they would accept this i have nothing of value in my home to pay for the debt i have done a budget sheet and can afford to pay them £20 a month for this debt. Im a bit worried in case i get an unreasonable bailiff at my door. the total is £566.57 advice would be great thank you.
