Hi, my name is alibee2006! P.I.P award dated wrong.

I was awarded P.I.P on 14/11/2017. The DWP sent my award back to the judge as my claim should have been from 16/3/2017 and not 27/6/2017 as stated by the judge. I've phoned the DWP numerous times and have been told it would be correct once the judge who issued the award corrects it. They said it could take upto 6 months. Surely I won't be waiting that long. As soon as would be much better. Anyone else had problems like this. Why can't they get the dates right. If they wanted something off us they'd be on us like vultures.
