I moved house on the 5th Feb and reported my change on the 5th Feb to the universal credit. I'm never moved house before while claiming so didn't know how it worked really but got confirmation also on the 5th that they had received my change of circumstances.
Fast forward to today I got a message off them saying that I need to bring a copy of my new tenancy agreement (fine) except they are saying they won't pay me any rent until I've provided this.
My assessment period is the 13th to the 13th so I've missed it by one day, I managed to get an appointment for today to take in the tenancy agreement but they are still saying as my assessment period is the 13th to the 13th there is nothing they can do about this month and I just won't get any rent paid?
How can they do that? It took them 9 days to get back to me and they are saying it's my fault it wasn't reported and proved within the assessment period. I'm already £250 in my overdraft and have a two year old to look after. 
Is there anyway I can take this further?
