CSA ARREARS

Hi All

I'm a newbie here was looking for some advice about the CSA !

Here is my story, myself and my ex divorced  back in 2016 we have a daughter and my ex went straight to the csa without out my knowledge, I tried to come to an arrangement with her and offered her £200 per month ( she already had to sons form her previous marriage and there Father paid £200  total per month for both of the boys) so £200 for my daughter seemed fair to me plus I would also buy clothes, school shoes etc etc ! But she decided she wanted the csa involved and wanted nothing but a DOE set up ! So from Dec 2016 the CSA started to take whatever they worked out I should pay and my company always paid it to them! Anyway to cut a long story short and get straight to the point my daughter has now left the nest and set up her own home with her partner ( way to young to be doing it in my eyes) and she's moved out if her mothers and now lives 260 miles away.

The CSA sent me a letter stating that I no longer need to make payments for my daughter but also said I have arrears of around £1300 !!!!!! Considering that I've had a DOE since Dec 2016 and never missed a payment I asked where the arrears came from only to be told that the would look into it and send me a breakdown that was 7 weeks ago ! How can they possibly say "our records show" without evidence to back this claim up ? My boss is taking £98.00 per week until the arrears are cleared ( currently stands at £400) I have payslips showing every payment taken out of my wages so someone somewhere is telling porky pies ! I phoned them today and after being on hold for 56 minutes I finally spoke to a lady who couldn't understand where them came from either and said for me to ring back in the morning and that she has marked my file so I get put through to a caes worker ! 

So my questions are

1 how can they say I have arrears without evidence?

2. If they are wrong will I get refunded
