Nonarrival of health professional for Ihome visit.

I had an appointment for a home visit from a H,P. today at 12.00 pm. She didn't arrive. My Mum phoned Capita 12.24,they tried to phone her but got no answer. Told us to ring back at 12.55, we did, they tried to phone her again,still no answer, but they left a message on her phone asking her to ring us,they said. Between 2.15 and 2.30 we rang them again. They tried to riing her again, then said they would get their manager to call her manager to find out what was going on.
At 4.30 we had a call from Capita to say that they had spoken to her and according to her she had both called at my house and also phoned me, but had had no reply from me in either case. The phone call I can perhaps understand, as Bt wre working on my phone line today, so it wasn't working every minute of the day, but both my mother and I were within 5 metres of my front door at all times, except when one of us went upstairs to the toilet,and the only knock at the door was fromthe BT engineer at about 11.50 this morning. My Mum was looking out the front window of the house between 11.52 and 12.10, and saw 2 cars stop, but they were both male visitors to other properties.
The problem is that the H.P. described the house accurately, so Capita say they can not make another appointment with me, and are refering my case back to DWP.

They have told me to contact DWP on Wednesday, to ask to have my case refered back to Capita again. I am concerned that DWP will blame me, and refuse my claim,and I am also very annoyed that my Mum hascome over from France to be with me for the medical, at the H.P.'s request, because when I spoke to the H.P. about the home visit I became very anxious, so she gave me her mobile number and told me to get my Mum to call her. When Mum did she asked Mum if she could come over to be with me for the medical.

Has anyone had a similar experience, or does anyone haveany advice?

My Mum is making these posts for me as I am severely dyslexic. We were advised to wait until Wednesday because it would take 2 working days to be refered back to DWP.
Because I suffer from PTSD after a very violent marriage, where I was the victim, I find it very difficult to deal with other people either on the phone or in person, this is why my mother came over from France for the medical. She has to return to France on Sunday. Do you think that the DWP will accept a call from her on my behalf? I have no friends that could talk to them for me and both my mother and sister live in France.
