I have repeatedly provided all required documents, including my end-of-year tax return, and completed every form as requested. Despite this, the Child Maintenance Service continues to make repeated mistakes, resulting in ever-increasing bills. The persistent errors suggest a systemic issue that needs urgent resolution. On top of this, I am told not to pay directly but to follow their unclear payment system. This level of service is unacceptable and needs immediate attention.They don’t do their job properly.
