Not claiming PPL, claiming baby bonus. When I called last week they said they hadn't noted on my file I had actioned maintenance for DD1 which I had a year ago, lucky I wrote down that reference number and they got Child Support people on the line like a 3-way? And said it was sorted, today I got a random payment saying "arrears" for $130 (my payment is usually next week or last week) then next week my payment has dropped from 170$ to less than 60$? How can there be an arrears and then we get less, doesn't seem to make sense to me! And still nothing for DD2?? No idea what is going on and the online letter I recieved didn't have any information other than the numbers...

ETA: the online letter also had my old address which I have updated both times I have called?
