Hi brooksy
You need to ring them again. I would have expected you to have received a letter offering you an extension at least until March 2021. Ask if an extension has been awarded so there is no break in your money. If they say no, ask for a call back from a case manager asking why you have not been offered an extension while they are dealing with your case like so many others have.
