Turns out they did indeed stop my money without telling me. Well, suspended it anyway. After I spoke to a lady in the Processing Dept on August 14th she sent me a form out to say what I'd be doing regarding my permitted work and it was dated the 17th August and said on the form I had 14 days to fill it in and return it. I posted it on Friday 24th evening once I knew what my boss had decided and thought I'd done everything asked of me. I haven't done any permitted work since the middle of August when my 52 weeks ran out either. A guy on the ESA line told me it had been suspended because that form hadn't arrived so I pointed out it had 14 days to return it on the form and nobody at any point said my money would be stopped if it wasn't back by my next payment date so he said Processing should have told me that. I said they hadn't and if they were the ones who suspended it I should probably talk to them so could I arrange a call back from them please and he said he'd ask but returned a minute later to say no I couldn't have them call me back until 4 working days had passed so the end of this week. By this point I was starting to really panic about my mortgage etc and asked him how I was expected to pay those things and obviously he didn't have an answer so just asked me if there was anything else he could help me with, I said no then we disconnected.
Shortly after it occurred to me I hadn't put a date on said form for when my reduced hours will start from because I didn't know which date to put (and thought I had 14 days for them to contact me and either request one or not) so I rang my local JC and spoke to a lady there who said she wouldn't have known which date to put either but I would need to call the ESA line again and ask them if I could give a date over the phone to prevent further delays. She also said she understood why I was annoyed and felt like I'm being punished for trying to work but they're very touchy about forms at DWP. I said if Processing had told me I would have hurried the decision along and got the form back in time but I didn't know they would just stop my money.
Rang ESA line again and a more efficient lady emailed Processing requesting a call back regarding the date issue and made sure she told them I stopped my upper limit hours middle of August so apparently they will ring me back within the next 24 hours. Unfortunately this lady ruined her competence by asking me for a mobile number which I gave but queried why and she said "so you're not tied to the house waiting for the call, perhaps you might want to go out and do your shopping". With what exactly??!! My bank is empty because I haven't been paid!!!!

I'd like to know how the staff in the Processing Dept would feel if at the end of the month their wages aren't paid and they have to wait days for them to decide when to release the money, I feel like an inferior human being just because they treat you as one for not being able to work. We have no rights.
So I've had to borrow money from a friend for my mortgage and ask another if they would mind picking me up a few bits from the supermarket when they next go to tide me over until I'm paid. I'm so peeved about this, I've had a kidney infection all weekend and I'm still wiped out from that so could have done without this nasty surprise. I can't believe they don't have to tell us they're doing this, she had 10 days after speaking to me to write and let me know but didn't bother to notify me at all. Disgusting treatment.
