Hello
Atos are hounding me really badly

I turned up in chronic pain for an assessment and passed out. The assessor told me I would not have to come back. This was changed and they re-scheduled the appointment
This was then changed by phone again and I was told due to GP evidence, I was awarded a taxi (as per last time) I also asked for it to be recorded at this point. He said someone would be back in touch to arrange another appointment when the recording equipment would be available (This man was nice)
The appointment was then changed again by phone. But the woman who called was bitchy and said she had no knowledge of my asking it to be recorded OR of my GP evidence (which was faxed) for a taxi. She flatly told me the new date is 10th December. So I told her, if it's not recorded and I have no taxi - then I will NOT be attending as I am too sick. I told her to make a note of this and she said someone would be back in touch - no-one has been.
I am bedridden due to pain most of the time due to major surgeries (more to come). Will my ESA (WRAG) be stopped if I don't attend? (which I cannot without a taxi to the door). Is it THEIR fault that no-one has been back in touch about this? And can I complain if my ESA is stopped? I am worried and it's not helping my health

It's making me worse.
