Can't say I've had any issues since being on it for the last few months other than being unfortunate enough to have a prat as a work coach.
I completely understand that they must be swamped with claimants. My dad worked at the job centre for 25 years, I know how stressful it can get, especially with what's happened this year.
But when you're interrogating someone (who has found their own work without any help or input from you), over the cost of their travel without even remembering where you're going to or from, you're just being a dick.
Spent about 15 minutes on the phone to them telling them what the cost of travel was (I had already sent the receipts) and that it was the cheapest available only for them to condescend, tell me I was wrong and that "it's actually your responsibility to look it up". Gave them the postcode of where I'm going from and to so they could look it up for their self. A couple of minutes of searching and then they obviously realised I was right and didn't say a word. Not the only instance of them talking to me like I'm a dickhead either, they seem to have an issue with every appointment.
I get that you have a massive workload and I get that you're probably used to a few piss takers but if you can't handle it then fuck off and find yourself a new job. I'd have literally run the risk of having my head caved in if I talked to people in my previous job like that. Maybe it's my fault for cutting them too much slack and not filing a complaint.
