Pip review form

Hi,
Just wondering if anyone could help, i have recieved my pip review form. I contacted welfare rights officer i know to complete this, he cancelled the appts 3 times on the day without warning and then said he hadn't arranged an appt but he had had sent me the appt via text message. He finally arranged the appt and said he wanted to change the descriptors as he thought i should get more points in some areas. I don't want him
to do this. I already qualify for enhanced by a lot due to the impact that my conditions have on me on a daily basis. They are progressive and there are no treatments that make any difference, i have tried it it you name it. He said he has never seen so much medical
evidence, he wouldn't be sending half
of it, He then told me that because i have a young baby this would be used against me, i explained that i have a lot of support from family/close friends etc. This has caused me alot of anxiety and stress. He then said he would complete the form after our telephone and send it off without me seeing it. He would then send me a copy once he had scanned it. I am really not happy about this and not sure what to do?. Any help/advice would be appreciated it. Thanks
