Health problem

I am just tired of trying get them to rectify my mobility claim since 27 July 2025. They keep on rejecting my claim saying I have exceeded my limit of one claim every three years. I have not claimed anything in 3 years. After many correspondence they told me this morning they have rectified it. When CE Mobility claimed again for a walker with brakes it was rejected again. My health has deteriorated and I need the walker. I just cannot understand their problem.
