ESA form waiting

wagner wrote: Hi. 2 years ago I was due a new ESA assessment. I never received any form to fill in and called the office after 2 months. I was told that my claim had been extended until July 2016. I'm now awaiting for a ESA form, and again nothing has arrived yet. I feel nervous waiting, worrying it might have got lost in the post. And I wonder whether I should call them to enquire or just let it go. I would like to know where I am at. The not knowing is always at the back of my mind.
Thank you very much.
