UPDATE : So i did what you all suggested and called them this morning, yes its a crossover, another letter is on its way, the lovely lady i spoke to has now told me my award is on going, for the next ten years anyway, something to be said for being a pensioner (probably the only thing), very grateful for this and thank you all for your replies xx
Sent in my PIP review form two weeks ago and have been waiting for the result, today i get a letter thinking it was that and they have extended it again to 3rd September 2021, so less than a year, i turned 66 in August and became a pensioner, so less than a year which mean i cannot change my car for the automatic i wanted (Struggling now with the manual). It says if you have had a review form but havent sent it back , you have a month, i sent it back two weeks ago duh!!
