Hi, I'm a new user and I'm here on behalf of my mum. And I'm sorry if this is long. Basically, a couple months ago she went to her doctor about ESA and, after asking her questions, he said she was eligable and wrote her a sick note from 1st August for 4 weeks. She took the sick note to the Jobcentre, told them what the doctor said and handed it in. They said that was fine and gave it back to her, but she thought that was just to keep for records or something. About when the 4 weeks were up, she realised she hadn't been paid ESA yet, and she had been living off of her last JSA pay. She went back to the doctor and he told her she had to post it off herself. He then wrote her another note from when the last one ended for 3 months. She then posted them both off at the same time. 3 days later she got a call saying they had recieved the note, but she hadn't made a claim yet (she thought she did that when she took the sick note in the first time), so she made one over the phone and they said she would be paid within 14 days. That was on 17th September and she hasn't been paid a thing. And just 2 days ago she got a letter saying her sick note was only from 1st Ausgust to 7th August and they need a new one if she wants to keep getting her benefit. Is there something she missed/didn't do? And although they said it would be backdated, it's been almost 10 weeks since the start of the first sick note. Will it still be backdated? Any advice would be brilliant as I have no clue about these things. And, again, sorry it's so long. Thank you
