hi i need help if anyone can , my partner has been on pip for two years at the lower mobility rate , she had her review on the 22nd march 2015 , on the 24th of june her award notice arrived and because her condition has worsened she was awarded the higher rate mobility , i then proceeded to order a car on mobility for her , i also telephoned pip and asked would her money be back dated to the time of her review being the 22nd march , i was told no as the award started from the 24th june , then today on the 25th july another award letter has been posted dated the 22nd june 2015 stating she is not entitled to the higher rate mobility following a review any help would be appreciated
