i received a letter today from tax credit-your your tax credits claim- is it right? then goes on to say i claim as a single person but we know a lot of people dont tell us about their partner...... i am a single parent and my circumstances have not changed since i renewed in april,does anyone know why i received this letter or has anyone received one of these. my ex minds my children for 4hrs each evening so i can work,pays maintenance and the sky bill!.I have tried to phone all day with no luck
