Yeah, its not strictly an aibu, they are bu and fucking arse twats.
We are going round and round in circles. They seem unable to understand that we are eligible due to ESA (so yet another shining example of how the world doesnt give a shit about disabled parents), even though its on their own website and the paperwork we sent off.
Getting hold of them is awful by email, if they bother to reply it takes at least 5 working days, and then (twice now) i have had the response that if i am claiming cause of jsa i need to call the job centre, if it is because of tax credits, you need to call them. It is neither, you fuckwits!!! 
I cant talk on the phone, dh has phoned them three times and tried to get some sense, yet they say there is no manager we can escalate our complaint to. They just keep saying that they have no confirmation of my claim, that it is their job to get - if they'd asked me for proof of income/disability/whatever, i would have bloody sent it.
To top it all off, if we get to 90 days since we applied, we have to start again from scratch.
Helping vulnerable families? Fucking liars.
So... Anyone else? Can anyone help me get it sorted?
