meglet, it was all plain sailing with the csa for me too.
then there was a few months when the payments dropped dramatically to nearly nothing and i phoned the csa. they were super efficient with phoning ex's employer etc. it turned out, after about 5 months on this 'reduced' payment, that my ex's employers were calculating incorrectly; his wage had not changed at all. not once did my ex say or ask me if his kids were ok with his shortfall or offer to pay the difference. he kept silent-tried to obviously dodge it. i never asked him about it. just goes to show. if no one was forcing him to pay, he would not be.
i know he will be the first man to put his hand up and say he will agree maintenance privately [so as not to pay the extra percentage and try to pay out less to his children]. he will also be the first person to muck it about, 4 weeks later. in the mean time, time gets wasted, we struggle and we all have extra unecessary stress etc etc.
we are fine as we are already without the governemnt forcing themselves into our private relationships and making me talk to someone who i dont want to talk to. i think, the last time i checked, it was up to me to go to mediation or not, it was up to me if i wanted to 'discuss' maintenece with him or not. not one person in this country will make me/put me through the stress of having to work out our finances 'together'.
