Momentum do not care about their disabled clients

My husband was diagnosed with Parkinson's in November 2017. He has been in hospital twice, had blood taken numerous times and all the necessary tests including the MOCA test. Our GP, neurosurgeon and Neuro psychiatrist have sent the necessary paperwork as he cannot work anymore. Emails are going backwards and forwards, depending stuff, receiving phone calls that that have sent the paperwork to the wrong dept and will resolve it and pay out his disability but yet nothing is done. Everyday I send an email and they now ignore me. My husband has had no income, has fallen 4 times already and cracked his ribs, Momentum don't care at all, we are just a cash *** that pays every month and that is it. Totally disgusted.
