Money in account, don't know why?

I checked my bank this morning. I have £222 that I was not expecting. I am not due PIP until fri 14th. I had a review and have been awaiting outcome. I am on enhanced living rate. I am wondering....hoping, I have been awarded mobility component but I am concerned that instead, my rate has been cut or even cancelled. I can't cope with calling them and my hubs is working.

Thank you. My hubs came home for a bit and called them. I have been re-awarded enhanced daily living and they have added enhanced mobility. I am pleased but a bit confused. They didn't award me with mobility 2 years ago but on this review, all we answered for that question was "there has been no change. ****** continues to struggle to make any journey unaided." and thst was it.
