1st letter arrives saying I will get a one off payment of £4374 next week and then massive amounts each month, realised it was wrong straight away but the next day... 2nd letter arrives telling me to ignore the 1st and that i will be getting £272 a month but that I have been overpaid by £4000!! When me and exDH seperated just after last renewal I was on my own with a 26k salary and childcare costs of £100 a week, and got approx £320 a month ...so was I overpaid!?! Can't get through on the helpline but will keep trying and put it all in writing I reckon.
