Since April this year ive been paying £80 too much too the CSA a month, It turns out that the Army informed them wrongly about the maximum they could take from my wage. As of next month the figure is being reduced back down. Am I entitled to ask for the overpayment back as It was through no fault of my own, or is a case of chin up and deal with it. Its not a huge figure but its still £640 which I need more than the army. Id ask my chief clerk this but im on leave and being speaking directly to JPAC to sort this out.
