Hi, was in receipt of PIP for my daughter (higher care/lower mobility). She has gradually improved enough for us to notify DWP in Feb 2017. They stopped all payments and finally has face to face interview in Sept. 17. Letter received today stating that PIP award ended 4 Nov 17, and they used this date as `we would not be expected to know the info they received would affect the award`. My question is should we now receive the PIP money from Feb 17 to 4 Nov? How do I chase up this money as it is almost £4000!!!
