Hello Eileen and welcome to the forum.
In case you did not know your full name seems to be showing. If you would like to change that there are instructions here.
My full name is showing, how can I stop it. Although the DWP vary in their response times I would have expected you to have heard by now. I would suggest that you give them a ring to find out what has happened. 0800 328 5644. If you ring first thing in the morning there are generally shorter queues.
I hope you get matters sorted out with them, but do come back to us if you want to,
Catherine
