Apparently it was sent in the post over a week ago (back to me so I could claim MA), but I haven’t received it. I desperately need it to claim MA from the JobCentre.
HR’s response is “well it must be lost then, we will send out a copy of the MATB1 we have here on file, along with a new SMP1 form” 
I’ve already had to remind them to send it as they hadn’t sent out back out to me and I went on Maternity Leave on the 17th October... Meaning I’m due to be paid a back dated payment from the 17th but I’m not even sure these type of payments get backdated!
I’m also aware that the claim takes 24 days to process, so if that’s correct, I’ll have no money for quite a while and I’m pulling my hair out about how to even pay my bloody bills.
What do I do now? Trying to get through to DWP but been on hold for 40 minutes now 
Will DWP even accept a photocopy of my MATB1? Won’t they want the original?
