Hi and thank you to anyone who reads this. I have an adult son with ASD, ADHD and OCD. When lockdown happened I had an ironing business so obviously couldn't work. I decided to try online selling but in the meantime I claimed UC. I had my father living with me but he died in May of that year. He had received Attendance Allowance and my son was on PIP., and I was/am his carer. I developed sacroiliac joint dysfunction so decided to end the ironing business.Fast forward to early this year I had a UC review. The agent noticed that I shouldn't be having non dependent deductions because my son was on PIP. I honestly didn't even realise that him being on PIP meant they couldn't deduct this money. I checked all my payments and sure enough the deduction had been made from every one. So I was expecting some back pay. I messaged them multiple times but they kept making excuses (I had another son living with me for a few months and they tried to say that it affected the situation) and then an agent told me to remove my son from my claim, re add him and it would ask if he gets PIP. I did all this and she sent it to a decision maker. This person told me I wasn't entitled to back pay because I reported the change too late!! It felt like the advice I was given was deliberate to void my claim for back pay. Then when I queried it the original agent said that on my original claim I had ticked no to the question about my son receiving PIP. I call BS on this, because there's no way that could have happened. It feels like somebody is covering up a mistake. I've been told there is no right to appeal because I reported the change too late but I only did what the agent told me to do! Does anyone know if there's anything I can do about this? If the shoe was on the other foot they'd be clawing the money back with no hesitation!
