Ex hasn't paid any child maintenance for about 4 months despite DS saying for a while that he has a new job. CSA says he's not declared any new job to them but on Sunday when DS's paternal gran dropped DS off she let it slip about him working (she mentioned him having to get a letter from his boss about something).
I asked if he was going to pay CSA now and she says he does pay, when I said he hasn't she then changed the story to he starts on Monday, then he's on a trial starting next week, then when I asked when he sees DS she says he doesn't finish work till 10pm on Friday and Saturday so sees him on a Sunday when he's off (even though he's apparently not started yet).
If I phone the CSA could they do anything about it as I've not got any of the work details and I am certain that if I ask the gran again for details she'll deny everything after speaking to ex?
