My cousin gets PIP of £68.1 per week. Last December she was told there would be a review around march as the award was up till the end of April. Nothing was sent through to her and the PIP has continued. She is now worried that they have missed the review and may stop the payments. I known nothing about how PIP works so can anyone advise? She can't get through on the phone. Do they do a review without sending out a questionnaire?
