Hi I've been separated a long time from my ex and we have a child who is 8. He stays at both our homes equally. It takes alot of time and effort to get money for things out of the ex. He owes me £100 which he told me he would place into my bank last week on a certain date. I still don't have it. He says he only has 20 to give me and I need to wait for the rest. We have a big expense next month we both have to go half on and I know I will have to chase again. Can I contact csa? Just getting a bit fed up.
