Very late PIP review

Just after Christmas this year I got the dreaded brown envelope letter , it had to be returned by Feb 2022 . I didn’t hear anything until June this year when I got a phone call from a lady who wanted to go through the form with me . Two months later I got a text saying ..
We still have your PIP form and will be progressing your review as soon as we can. You may still need an assessment with a health professional. Your PIP will continue to be paid until we review your claim. You only need to contact us if your circumstances change.
And have continued to get these texts every couple of months , just received another one yesterday ! Has anyone else had this ?

I’m still getting paid so that’s a plus but a worry too

Many thanks
